摘要：
A series of two-dimensional conjugated polymers (P1–P4) based on benzo[1,2-b:4,5-b’]dithiophene donor unit and thiophene unit modified by pendant acceptor groups were synthesized. P1–P4 possess good solubility, thermal stability, tunable optical properties and low HOMO energy levels. Bulk heterojunction polymer solar cells based on P2 exhibit a power conversion efficiency of 1.89% and an impressively high Voc of 0.93 V.[graphic not available: see fulltext]
