摘要：

Two wide-bandgap copolymers (PBD and PBD2T) containing dithieno[3,2-b: 2',3'-d]pyridin-5(4H)-one units were designed. They have large optical bandgaps and deep HOMO levels. Solar cells based on them and a nonfullerene acceptor IT-M gave high open-circuit voltages up to 1.00 V and decent power conversion efficiencies up to 10.34%.
