设计并合成了三种不同端基的噻吩并[3，2-B]噻吩类低能带隙非富勒烯受体化合物TTIC-M、TTIC和TTIC-F。以宽带隙聚合物PBDB-T为施主，在300-900 nm范围内形成互补吸收，TTIC-M、TTIC和TTFC-F基光伏器件的光电转换效率分别达到9.97%、10.87%和9.51%，短路电流超过21 mA·cm ~（-2）。
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 over 21 mA cm(-2).
