33 - 129Thermal Behavior of Diynes with Formally Conjugated Heteroaro-matic Sidegroups. — Diynes with heteroaromatic sidegroups directlylinked to the acetylenic backbone are found to show liquid crystalline behaviorupon heating. These diynes also undergo polymerization in their liquid crys-talline state, although the polymers so formed do not show liquid crystallinebehavior. — (SARKAR, ABHIJIT; TALWAR, SATYA S.; Bull. Chem.
