Poly[3-(5-octyl-thienylene-vinyl)-thiophene]: A side-chain conjugated polymer with very broad absorption band

Abstract
A novel polythiophene derivative, poly[3-(5-octyl-thienylene-vinyl)-thiophene] (POTVT) with conjugated thienylene vinyl side-chain, was synthesized, and the POTVT film shows a very broad absorption band-width covering from 300 nm to 700 nm after thermal annealing at 130 °C for 10 min.
