Synthesis and Structure of Regioregular Poly(1,4-arylene) Bearing a Chiral Substituent

摘要

We have reported that cross-coupling polymerization of bromo(chloro)benzene bearing different substituents at 2- and 5-positions takes place successfully with nickel(Ⅱ) catalyst to synthesize unprecedented regioregular poly (1,4-arylene). Herein we describe synthesis of regioregular poly(1,4-arylene) bearing a chiral substituent suggesting chirality-induced higher order orientation of the polymer structure such as helix structure.
