Alternating poly(pyridyl vinylene phenylene vinylene)s: Synthesis and solid state organizations

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.

Synthesis of Substituted 1,4-Divinylbenzenes by Heck Reactions with Compressed Ethene

Substituted 1,4-divinylbenzenes 3a-i were synthesized by twofold Heck coupling from the corresponding 1,4-dibromo- (electron withdrawing substituents) or 1,4-diiododialkoxybenzenes 1a-i and ethene. Oligomerizations could be suppressed by increasing the pressure of ethene to 30 bar, simultaneously improving the yields of the title compounds.
