摘要：

A new alternating donor-acceptor (D-A(1)-D-A(2)) copolymer containing two electron-deficient moieties, isoindigo and quinoxaline, was synthesized. The photovoltaic performance of this polymer could be improved by incorporating fluorine atoms into the quinoxaline units, resulting in an efficiency of 6.32%. This result highlights the attractive promise of D-A(1)-D-A(2) copolymers for high-performance bulk heterojunction solar cells.
