摘　　要：The A–D–A′–D–A-type non-fused ring electron acceptors(NFREAs),consisting of electron-donating unit(D)as the bridge to link electron-accepting units(A and A′),have emerged as promising electron acceptors for organic solar cells(OSCs)and organic photodetectors(OPDs).As the units are linked by the carbon–carbon single bonds,these electron acceptors generally possess feasible synthesis and tunable optoelectronic properties.Herein,the recent progress of A–D–A′–D–A-type NFREAs is reviewed,including molecular design,device performance,structure–property relationships,and their applications in OSCs and OPDs.Finally,we discuss the challenges and propose the perspectives for the further development of A–D–A′–D–A-type NFREAs.A–D–A′–D–A型非稠环电子受体(NFREA)是由给电子单元(D)桥连不同的吸电子单元(A和A′)组成.由于给/吸电子单元之间通过碳-碳单键连接,A–D–A′–D–A型非稠环电子受体通常具有合成简单、光电性能易于调控等优点.近年来,其在有机太阳电池(OSC)和有机光探测器(OPD)领域,逐渐成为一类非常有潜力的电子受体.本文系统回顾了A–D–A′–D–A型非稠环电子受体的进展,包括分子设计、器件性能、结构-性质关系,以及其在OSC和OPD中的应用.最后,本文讨论了该类电子受体当前所面临的挑战,并展望了其未来的发展前景.
