History of the Dayton Section of the American Chemical Society The beginnings of the Dayton Section date back to 1929. The first official Chair of the Section was Dr. C. A. Thomas, who served from 1931-1932. Our current membership is about 450, covering the counties of Montgomery, Greene, Miami, Clarke, Preble, and Darke. Section meetings, featuring national and local speakers, are held quarterly and include a local poster session. In addition, the last meeting of the year honors the 50-year and 60-year members. The Section has a long history of administering local philanthropy:

The Patterson High School Chemistry Awards go to winners of the Patterson High School Chemistry Competition, which consists of two stages: examination and essay. First, second, and third prizes are $1000, $750, and $500. Originally established by Charles A. Thomas and Carroll A. Hochwalt, former Dayton chemists and Monsanto researchers, the top chemistry students in the area have been recognized since 1943. In 1990, the family of the late Austin M. Patterson, also a prominent Dayton chemist, assumed sponsorship.

Last year, a new competition was offered to encourage high school students who have an interest and aptitude in chemistry to persist in their STEM education. This competition is open to any chemistry student enrolled in one of the high schools within Dayton City Schools. The Marie Daly Award is named for Marie Daly, who in 1947 became the first African American woman to earn a Ph.D. in chemistry. This competition will be continued this year.

Recipients of The Patterson College Chemistry Awards are chosen by the faculty of each of the universities within the Dayton Section from their outstanding junior chemistry majors using the general criteria of scholarship, character, extra-curricular involvement, and potential for success after college. Winners receive a certificate of recognition and a check for $400.

The Patterson-Crane Award was originally established in 1949 as the Austin M. Patterson Award to acknowledge meritorious contributions to chemical literature and documentation of chemistry. Dr. Patterson was the first recipient for his work as editor of Chemical Abstracts from 1909-1914. The biennial award was expanded in 1975 to honor another Chemical Abstracts editor (1915-1958) and 1953 award recipient, E. J. Crane. The award, which includes a monetary honorarium, is now funded by a bequest of the Patterson family, by the Helen G. Crane Fund of the Columbus Foundation, and by the Patterson-Crane Award Fund of the Dayton and Columbus Sections.

The Dayton Section also participates and supports the Dayton/Miami Valley TechFest,

and contributes funds and judges for the West District Science Fair.

History of the Society for Applied Spectroscopy

The Society for Applied Spectroscopy (SAS) is a non-profit, international, professional membership organization for scientists in all fields of spectroscopy, including physics, chemistry and other allied sciences. SAS is dedicated to those interested in all phases of spectroscopy: the science and art of light absorption, light emission, Raman scattering, and related forms of light-matter interaction for determining the composition and structure of matter.

History of our Host Venue

The history of Central State University, an 1890 Land-Grant Institution begins with our parent institution, Wilberforce University (WU), named in honor of the great abolitionist William Wilberforce. Established in 1856 at Tawawa Springs, Ohio, WU is affiliated with the African Methodist Episcopal Church and is one of the oldest Black-administered institutions of higher education in the nation. In 1887, the Ohio General Assembly enacted legislation that created a Combined Normal and Industrial Department at Wilberforce University. The objectives of this new state-sponsored department were to provide teacher training and vocational education, and to stabilize these programs by assuring a financial base similar to that of other state-supported institutions. The statue establishing the Combined Normal and Industrial Department declared that the institution was “open to all applicants of good and moral character” thereby indicating no limitations as to race, color, sex, or creed. It was clear, however, that the Department and its successors were designed to serve the educational needs of African-American students. Although this Department operated as part of Wilberforce University in most respects, a separate board of trustees was appointed to govern the state-financed operations. In 1941, the department expanded from a two- to a four-year program, and in 1947, it legally split from Wilberforce, becoming the College of Education and Industrial Arts at Wilberforce. The name was changed in 1951 to Central State College, and in 1965, the institution achieved university status. The University has grown steadily since its’ founding. In recent years, it has added new academic programs, established a new College of Science and Engineering, constructed a new academic building, four new residence halls, and began the construction of a new University Center scheduled for completion in Fall 2015. In February 2014, the 113th Congress of the United States designated Central State University an 1890 Land-Grant Institution. This designation is a distinct recognition for an Ohio institution of higher education, and Central State is one of two institutions to hold this distinction. The major impetus of the designation is to provide access to education and to promote opportunities for students with interest in Science, Technology, Engineering, Mathematics and Agriculture (STEM-A) integrated through all academic disciplines. In tandem with progressive academic achievement, the University has embodied tenets of Service…Protocol…Civility®. Its faculty, staff, and students will provide service to the institution, and various communities for the greater good; be guided by protocol and adherence

P a g e | 4

to best practices in order to gain desired results; and actively demonstrate civility with the understanding that respect for each voice is essential to a learned society. Much more has changed at Central State University throughout its history. However, one constant is the commitment to providing an excellent, affordable education to the residents of Ohio and beyond. In concert with the mission of the University, Chemistry faculty foster the professional development of students through academic excellence, and provide educational opportunities to students to be competitive in a technological society. The specific objectives of the discipline are to provide students with; 1) a thorough understanding of basic and modern concepts of chemistry and 2) the ability to analyze and apply chemical concepts to technical problems through the development of laboratory skills. Opportunities exist for undergraduate research experience, both on campus and through summer internships. Development of a strong sense of professionalism, with the motivation to pursue graduate study is encouraged. Professional programs include preparation for dental, medical, pharmacy and veterinary schools. An option in forensic science will prepare students for jobs or graduate school in forensic science. The program leads to a Bachelor of Science; in addition, a student may receive a B.S. degree in Secondary Education in middle school education in the Physical Sciences. 129 Years of Service and Excellence 1887–2016 The Dayton Section of the American Chemical Society thanks Provost and Vice President for Academic Affairs, Charles Wesley Ford, Jr., Ph.D., Chemistry Department Interim Chair, Dr. Ibrahim Katampe, as well as all the department faculty and students of Central State University for welcoming, hosting, and providing support for the 2016 ACS Poster Session.

Abstract

Insulating SiO2 films can be produced by hydrolysis of metal alkoxide

tetraethylorthosilicate (TEOS) in the presence of an acid catalyst in supercritical CO2 (sc-

CO2). SiO2 films are formed on substrates using TEOS as a source of silicon, and acetic

acid (HAc) as a catalyst. The chemical equation of the SiO2 film formation can be

expressed as Si(OCH2CH3)4 + 2H2O -- SiO2 + 4CH3CH2OH. Water required for the

hydrolysis is from in situ generation of esterification reactions involving HAc and the

alcohol produced. Without the catalyst, the hydrolysis of TEOS proceeds very slowly.

The acid catalyzed deposition reaction actually starts at room temperature but produces

decent films in sc-CO2 at moderately high temperatures. Supercritical CO2 is known to

have near zero surface tension and provides an ideal medium for fabrication of SiO2

films. Formation of SiO2 films via hydrolysis in sc-CO2 is more rapid compared to the

traditional hydrolysis reactions at room temperature. Metal alkoxide hydrolysis reactions

carried out in a closed sc-CO2 system is not affected by moisture in air compared with

traditional open-air hydrolysis systems. Using sc-CO2 as a reaction medium also

eliminates undesirable organic solvents utilized in traditional alkoxide hydrolysis

reactions. The ATR-FTIR, EDS, XRD, XPS spectroscopy, and electron diffraction (ED)

measurements were conducted to characterize the films. XRD and ED measurements

demonstrated the SiO2 films produced were amorphous. EDS, ATR-FTIR and XPS

spectra showed elemental composition of the films formed on the substrate surfaces to be

SiO2. The amount of catalyst on the film thickness is discussed.

Abstract

A series of poly(arylene ether)s was synthesized by the nucleophilic aromatic

substitution (NAS) polycondensation reactions of N,N-dialkyl-2,4-

difluorobenzenesulfonamide and N,N-dialkyl-3,5-difluorobenzenesulfonamide. The

sulfonamide-activated monomers were synthesized by reacting 2,4- and 3,5-

difluorobenzenesulfonyl chloride with a series of dialkyl amines, ranging from n-propyl

to n-octyl. The poly(arylene ether)s, prepared with bisphenol-A as the nucleophilic

reaction partner, were characterized by 1H and

13C NMR spectroscopy, TGA, DSC and

SEC. The thermal properties of the N,N-dialkyl-2,4-difluorobenzenesulfonamide

polymers were compared to those of the N,N-dialkyl-3,5-difluorobenzenesulfonamide

system. Poly(arylene ether)s prepared from the 2,4-monomers possessed consistently

higher glass transition temperatures than those from the 3,5-monomers. While the 5%

weight loss temperatures were similar for both systems, there were observable differences

in the TGA traces, indicating that the decomposition pathways may not be the same.

Synthesis of Functionalized PEEK Analogues via “One-Pot” Synthesis

Zachary Ewing1 and Eric Fossum Wright State University

ewing.51@wright.edu

1Graduate Student Presenter

Abstract

Poly(ether ether ketone), PEEK, is known for its high thermal stability, chemical and

corrosion resistance, and versatility. When functional groups are introduced to PEEK,

crystallinity is often disrupted causing some of the desirable properties to diminish.

Synthetic routes that allow functionalization, but permit the crystallinity to be maintained

are highly desirable. This presentation will focus on our attempts to prepare functional,

semi-crystalline PEEK analogues. The overall project has two goals: 1) to demonstrate

semi-crystalline properties in copolymers of PEEK with pendent functionalization sites,

and 2) to synthesize copolymers of PEEK with pendent functional groups. The optimum

percentage of traditional PEEK in the copolymers was investigated, as was the

importance of the monomer addition order. The level of crystallinity was determined via

DSC and X-ray diffraction analyses. Copolymers of PEEK containing up to 25 % of

repeat units derived from 3,5-difluorobenzophenone remain semi-crystalline, but with

better solubility than PEEK.

A Sequence Comparison of Cytochrome Oxidase I in Hadenoecus

cumberlandicus populations found in the Sloans Valley Cave System, Pulaski

County, Kentucky

Rebecca Holmes1

and Brandon Miner1

1Undergraduate Presenter(s)

Abstract

Sloan’s Valley Cave, located in Pulaski County, KY, is one of the largest cave

systems in the Cumberland Plateau, with at least 39 km of documented passage and 16

entrances. The distribution entrances throughout the system, allow for a greater diversity

of organisms to enter and exit the system, contributing to the balance of the cave's

ecosystem.

Hadenoecus cumberlandicus is one of several troglophiles that inhabit the Sloan’s

Valley Cave. These crickets migrate within the cave throughout the year, staying deeper

in the system during cold months and closer to an entrance during warm months. At each

point of their migration these crickets may have contact with outside populations; other

entrance populations at interior cave locations in the cold months, and exterior

populations from neighboring caves during warm months. These outside contacts allow

for interbreeding of the populations, increasing the genetic diversity of a given entrance

population.

After collecting samples of H. cumberlandicus from five entrances, DNA was

purified from a single hind femur from all collected samples. Regions of the COXI gene

were amplified by PCR. Four of the ten UEA primers within the 1500bp segment were

selected to produce two overlapping fragments to be used later to sequence about one-

fourth of the gene. Amplification with primers UEA7 and UEA10 selected a 550 bp

fragment and primers UEA5 and UEA8 selected a 220 bp fragment . The PCR products

were purified, with a yield of 2.71∗10 2ng/μl determined by Abs 260 . Sequencing of

these purified amplification products permits identification and analysis of single

nucleotide polymorphisms (SNPs) to assess the genetic variability within and among the

populations and determine the level of genetic mixing.

Graduate Award Presenter(s): S. Mira and R. Stachler

Abstract

Wood is one of the largest renewable biomass energy resources used today, yet it is not

necessarily a clean source of energy. The combustion process of wood is largely

unoptimized, as it is inherently multidimensional and multi-phase, and the formation of

emissions such as CO, NOx, and other particulates are results of both deficient and

copious mixing. Thus, standard experiments characterizing the emissions/speciation and

performance of wood combustion using various fundamental and applied experimental

configurations can contribute in part to the reduction of emissions and increases in

efficiency. Previous studies focused on experimental configurations similar to so-called

stove combustion (i.e. multiphase, multidimensional). This model reduces computational

and experimental complexity and simulation cost, while validating wood combustion

apparatus designs. Here, we discuss an experimental configuration in which the

initial/boundary conditions are both well-characterized and entirely gaseous, and the

geometry can be modeled as zero or one-dimensional. Thus, a preliminary study of gas-

phase wood specific species was conducted in order to design and speculate the potential

benefits of these reduced order experimental configurations. The study consists of

building a model capable of producing results for one of these configurations, a

counterflow diffusion flame experiment, validated by existing and established

experimental results. The developed model will be used to produce results for dry

hardwood following the work of Ranzi et al. (Ranzi, Couci, Faravelli, et al., 2008).

Future work will be building the established experimental counterflow diffusion flame

apparatus to validate the dry hardwood model and to build more comprehensive biomass

kinetic mechanisms.

Abstract

Diagnostic testing is widely unavailable in the developing world due to a lack of

healthcare, medical instruments and health professionals. As a result, there are great

needs for diagnostic tools with low fabrication costs, ease of interpretation, and

compatibility with low sample volumes. An integrated paper based device with flow

directed by hydrophobic wax channels and propelled by capillary action has been

developed allowing for plasma separation from whole blood through a plasma separation

membrane, detection of a targeted biomarker (IgG) down to 0.05 mg/mL, easy handling

for the user and low fabrication costs. Using gold nanoparticles (AuNPs), which exhibit

colorimetric properties, the detection of proteins in the blood can be made possible by

linking the AuNPs to antibodies corresponding to the targeted biomarker using gold

nanoparticle-based colorimetric sandwich immunoassay. In the design and fabrication of

the integrated device, the amount of antibodies and AuNPs to functionalize the paper

substrate were modified. With further modification, this platform can be used to test for a

multitude of biomarkers in the body.

Undergraduate Award Presentera

Abstract

Following published procedures, carboxybenzenediazonium and

nitrobenzenediazonium ions were synthesized in the presence of carbon particles. Cyclic

voltammetry of the product solution showed characteristic diazonium reduction peaks

and carbon paste electrodes made from the modified carbon particles showed evidence of

nitrophenyl groups, suggesting that this method is successful in grafting the carbon.

Bare carbon and grafted carbon particles, as well as commercial SPE tubes, were

compared for their ability to trap copper (II) and lead (II) ions. Acid-eluted metal ions

were quantified with flame atomic absorption spectroscopy. Initial results show no

significant difference for copper and lead extraction on unmodified vs. carboxybenzene-

grafted carbon particles. Both unmodified and carboxybenzene-grafted carbon particles

showed about 90% recovery for copper(II) (0.2 mg/L) and lead(II) (0.5mg/L), while

commercial tubes had recovery of about 30% at low level concentrations and 0.4% for

higher level concentrations of lead(II) solutions. Concentration factors of up to 20 were

achieved.

Abstract

Vanillin has many interesting properties and is frequently used as a building block in

organic synthesis. Poly(ether ether ketone)s (PEEK) have been known to exhibit thermal

stability, solvent resistance, and excellent mechanical properties. A series of

dioxyalkylene based monomers containing vanillin subunits were generated via a three-

step process, 1) a Williamson ether synthesis, 2) a Grignard reaction with p-

bromofluorobenzene, and 3) a Jones oxidation. The monomer was then polymerized in an

A2B2 Nucleophilic aromatic substitution (NAS) polymerization with Bisphenol-A. The

polymers exhibited thermal stability with 5% weight loss occurring at about 390 °C and

Tg occurring around 100 °C.

1Graduate Award Presenter

Abstract

Bifunctional monomers, monomers containing two distinct polymerizable moieties, aid in

pre- or post polymerization functionalization. This project seeks to develop bifunctional

monomers in which one of the polymerizable moieties can undergo nucleophilic aromatic

substitution (NAS) reactions. The overall project has two goals: 1) to synthesize

bifunctional monomers, such as N,N-diallyl-3,5-difluorobenzenesulfonamide, and 2) to

form polymers using acyclic diene metathesis (ADMET), radical cyclopolymerization,

and NAS, followed by the appropriate functionalization chemistry. The monomers were

prepared via the reaction of diallyl amine with the appropriately substituted

benzenesulfonyl chloride. The ADMET and radical cyclopolymerizations were

monitored by 1H NMR spectroscopy, observing the disappearance of signals for the allyl

groups and the appearance of broad aliphatic signals. The polymers formed via NAS

reactions were followed by DEPT 90 13

C NMR spectroscopy. Additionally, GPC, DSC,

and TGA were used to characterize the polymers, which indicated successful ADMET,

cyclopolymerization, and NAS reactions.

Abstract

Colorants are used to modify the color of commercially manufactured natural and

synthetic materials. Natural dyes have been used by numerous ancient cultures to dye

handmade goods. Natural dyes extracted from sources containing anthocyanin will have

color variations based on the pH of the dye solution and substrate. Understanding how

the pH affects natural dyes during extraction and application will allow more variety of

colors to be produced and will expand their relevance to manufacturing materials. To

examine how pH affects the colors of natural dyes during extractions and to investigate

how pH affects the color of natural dyes on different substrates, natural dyes were

extracted from several plants using a variety of methods. The pH was modified during

and after the extraction process. The resultant dyes were analyzed by UV-Vis

Spectroscopy and then applied to natural fibers and bioplastics. Results will be presented

and discussed.

Abstract

Colorants are used to modify the appearance of commercially available manufactured

materials. At least 66% of all colorants are of the azo type. Azo dyes are a nitrogen-

containing compound created by combining a diazo aniline and a coupling agent during a

coupling process where pH has been observed to modify the resulting color.

Understanding how the pH affects the azo dye during all stages of the synthesis process

will enable a greater matrix to be developed, tested, and modeled relative to natural dyes

thereby expanding their manufactured end use possibilities. Thus, various azo dyes were

synthesized inhouse, modifying the pH throughout different steps in the process to

examine how pH affects the colors of azo dyes during synthesis. The resultant dyes were

analyzed by UV-Vis Spectroscopy and then applied to natural fibers and bioplastics to

investigate how pH affects the colors of azo dyes versus natural dyes on different

substrates. Results will be presented and discussed.

Abstract

Civilizations have extracted colorants from organic sources, with the earliest found in

prehistoric cave paintings. The first recorded mention of fabric dyeing was using natural

pigments mixed with water and oil to decorate skin, jewelry and clothing. The synthetic

organic chemistry industry began preparing the dye mauve from coat-tar chemicals.

Today, most clothing is dyed synthetically, with synthetic azo dyes being the most

predominant. Synthetic dyes are cheap to produce, do not vary batch to batch, and will

dye a wide range of substances. However, chemical dyeing can cause significant

environmental degradation and harm to workers when not handled properly. The

wastewater from textile plants is classified as the most polluting of all industrial sectors

with dye wastewater becoming one of the substantial sources of severe pollution

problems. Toxic chemicals are absorbed into the skin of the workers when they come

into prolonged contact with the synthetic dyes. A return to the use of natural dyes and

bioplastics would benefit both the workforce and the planet. Natural dyes from various

plants were extracted using aqueous materials. Diazo dyes were synthesized from

phenol, naphthol, and resorcinol. The isolated dyes were characterized using UV-Vis

Spectroscopy and applied onto fibers and bioplastics. The dyed materials were further

evaluated for stability using fastness testing. Results will be presented and discussed.

We are reporting the preparation and studies of some novel structures, containing one

(compounds 1,3) or two phosphonate moieties (compounds 2,4), connected to a central hydrazo

or azo core. These are some of a series of P – N containing compounds, that are being prepared

and studies by us in terms of their potential as reactive flame retardants. However, both classes

of substances are unknown and this has necessitated thorough structural investigation.

Preparation of the hydrazophosphonates 1,2 was achieved via interaction of the

corresponding carbazates or phosphonyl hydrazines with the appropriate phosphoryl chlorides.

The resultant hydrazophosphonates were further oxidized with either N-bromosuccinimide

(structures 1) or lead tetraacetate (structures 2), leading to the corresponding azophosphonates

3,4. The azo compounds have been the subject of detailed structural investigation, including

single crystal X-ray, thermal decomposition and kinetic studies, and elaborate theoretical

analysis. We have also started studies of their reactivity in cycloaddition (Diels-Alder type)

reactions.

Abstract:

A series of poly(aryl ether)s with varying percentages of ammonium groups,

located on truly pendent positions, was prepared and characterized. The initial polymers

were prepared by nucleophilic aromatic substitution (NAS) polycondensation reactions of

varying ratios of 3,5-difluorophenylsulfonyl toluene and 4,4’-difluorodiphenylsulfone,

with bisphenol-A as the nucleophilic reaction partner. The tolyl groups in the resulting

polymers were subjected to radical bromination with N-bromosuccinimide, followed by

amination with three different amines: trimethylamine, dimethylhexadecylamine, and N-

methyl-imidazole. The polymers were characterized by 1H and

13C NMR spectroscopy,

thermogravimetric analysis, and differential scanning calorimetry. With the exception of

the 100% functionalized polymers, tough films were observed after casting from

solutions in dimethylformamide. The films were evaluated for potential use as alkaline

exchange membranes (AEM) by determining their water uptake and ion exchange

capacity values.

Poly(ether ether ketone)s – PEEK polymers are known for their unique properties

including excellent thermal stability, solvent resistance and mechanical properties. Since

their discovery, various alterations have been done to enhance its properties. A series of

Poly(ether ether ketone)s – PEEK monomers have been synthesized via a three step

process involving oxyalkylene dibenzaldyde synthesis, Grignard reaction to aid the

addition of benzofluoro groups and subsequent oxidation to form a ketone.

Polymerization occurred in an A2+B2 fashion with Bisphenol-A under NAS conditions

(NMP, Toluene, Potassium carbonate). Previous work has shown the synthesis of para

substituted PEEK systems that formed flexible, colorless, transparent films, and exhibited

excellent thermal stability. Current research investigates synthesizing similar PEEK

systems with meta substituted oxyalkylene linkages.
