Abstract

Fluorescent poly(phenylene vinylene)s and poly(phenylene ethynylene)s contg. rigid triptycene groups were prepd. using Suzuki and Sonogashira protocols. The triptycene groups impart extraordinary soly. to conjugated polymers even in the absence of flexible side chains; addnl. t-Bu groups were introduced, which were found to further enhance soly. Stable solns. of poly(phenylene vinylene)s and poly(phenylene ethynylene)s in nematic liq. crystal 1-(trans-4-hexylcyclohexyl)-4-isothiocyanatobenzene (6CHBT
