Abstract

Abstract : Nonfullerene acceptor FDICTF (2, 9‐bis(2methylene‐(3‐(1, 1‐dicyanomethylene)indanone))‐7, ​12‐​dihydro‐​4, ​4, ​7, ​7, ​12, ​12‐​hexaoctyl‐​4 H ‐​cyclopenta[2″, ​1″:5, ​6;3″, ​4″:5′, ​6′]​diindeno[1, ​2‐​ b :1′, ​2′‐​ b ′]dithiophene) modified by fusing the fluorene core in a precursor, yields 10.06% high power conversion efficiency, and demonstrates that the ladder and fused core backbone in A–D–A structure molecules is an effective design strategy for high‐performance nonfullerene acceptors.
