摘　　要：近几年,受益于稠环电子受体材料的蓬勃发展,有机太阳能电池的能量转换效率从富勒烯时代的12%迅速提高到非富勒烯时代的20%.其中,非对称结构的分子设计策略发挥了重要作用.本文按照稠环骨架、末端基团和侧链3种非对称分子设计策略,综合评述了非对称稠环电子受体的研究进展,并讨论了其中的结构-性能关系;最后,对非对称稠环电子受体的未来发展进行了展望.Benefiting from the development of fused-ring electron acceptors(FREAs),power conversion efficiencies of organic solar cells have rapidly increased from 12% for the fullerene era to 20%for the non-fullerene era.The asymmetric molecular design strategy plays an important role in the enhancement of photovoltaic performance.In this paper,we review the research progress of asymmetric FREAs according to the following three kinds of molecular design strategies:the asymmetric fused-ring backbone,asymmetric end groups and asymmetric side chains,discuss the structure-property relationship,and finally provide an outlook on the future development of asymmetric FREAs.
