Through-space conjugated polymer containing 2.2paracyclophane and dithiafulvene units in the main chain

摘要

A new through-space conjugated polymer containing alternate [2.2]paracyclophane and dithiafulvene units was synthesized by cycloaddition polymerization of aldothioketene derived from 4, 16-diethynyl[2.2]paracyclophane. The obtained polymer was soluble in common organic solvents and could form thin films. UV–vis absorption spectrum of the polymer revealed that its conjugation length increased due to the through-space interaction of the [2.2]paracyclophane units. The polymer formed a charge transfer (CT) complex with 7, 7, 8, 8-tetracyanoquinodimethane (TCNQ) in DMSO.
