Abstract

Poly(pyridylvinylenephenylenevinylenes) were synthesized by Heck coupling procedures. These materials display large red shifts in their optical absorption which upon protonation of alkylation of the pyridyl nitrogen. Some of the polymers were found to be liq. cryst. The protonated or alkylated versions exhibit highly organized structures due to charge-transfer interactions between polymer chains. [on SciFinder(R)]
