Abstract
Poly(pyridyl vinylene phenylene vinylenes) were synthesized by Heck co upling procedures. These materials display large red shifts in their o ptical absorption which upon protonation or alkylation of the pyridyl nitrogen. Some of the polymers were found to be liquid crystalline. Th e protonated or alkylated versions exhibit highly organized structures due to charge-transfer interactions between polymer chains. (C) 1997 Elsevier Science Ltd.
