Abstract

Low band-gap polythiophene (PT) derivatives, with bulky conjugated side-chains composed of the triphenylamine, thiophene, and vinylene groups (TPATh), are synthesized. The copolymers, synthesized by Grignard metathesis and Stille coupling with different copolymer configurations and side-chain densities, are regioregular-TPATh-PT (rr-TPATh-PT) and random-TPATh-PT (r-TPATh-PT), respectively. The incorporation of bulky conjugated ...
