Summary:本文设计合成了基于噻吩[3,2b]噻吩稠环受体具有不同末端基团的三个窄带系非富勒烯受体TTIC-M,TTIC和TTIC-F.采用宽带隙聚合物PBDB-T为给体在300–900 nm光谱范围内形成了互补光吸收,基于TTIC-M,TTIC和TTIC-F的光伏器件分别获得了高达9.97%,10.87%和9.51%的效率和高达21 mA cm^-2的短路电流密度.

Three low bandgap non-fullerene acceptors based on thieno[3,2-b]thiophene fused core with different ending groups, named TTIC-M, TTIC, TTIC-F were designed and synthesized. Using a wide bandgap polymer PBDB-T as donor to form a complementary absorption in the range of 300–900 nm, high efficencies of 9.97%, 10.87% and 9.51% were achieved for TTIC-M, TTIC and TTFC-F based photovoltaic devices with impressively high short circuit current over21 mA cm^-2.
