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