摘要

Abstract Six alternating conjugated copolymers (PL1–PL6) of benzo [1, 2-b: 4, 5-b′] dithiophene (BDT) and thiophene, containing electron-withdrawing oxadiazole (OXD), ester, or alkyl as side chains, were synthesized by Stille coupling reaction. The structures of the polymers were confirmed, and their thermal, optical, electrochemical, and photovoltaic properties were investigated. The introduction of conjugated electron-withdrawing OXD or ...
