Pyran is fused into the planar donor moiety to enhance the extinction coefficient and reduce the bandgap, thus two acceptors PTTIC and PTBT-R are designed and synthesized. Compared to the IDT-based acceptor, these pyran-bridged acceptors show higher the highest occupied molecular orbital level and wider absorption coverage. Devices fabricated with poly[(2,6-(4,8-bis(5-(2-ethylhexypthiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene)-co-(1,3-di(5-thiophene-2-yl)-5,7-bis(2-ethylhexyl)-benzo [1,2-c:4,5c']dithiophene-4,8-d ione)] (PBDB-T):PTTIC as the active layer give a power conversion efficiency (PCE) of 7.35%.
