side-chain isolated polythiophene derivatives, PT4TV and PT4TV-C, were designed and synthesized by copolymerization of thiophene unit with thienylene–vinylene (TV) conjugated sidechain and unsubstituted terthiophene unit. The difference of the two polymers is an additional carbonyl group on the conjugated TV sidechain in PT4TV-C. Compared to previous reported conjugated sidechainpolythiophenes (CSC-PTs)
