Synthesis and Photovoltaic Properties of a Tricyanated Perylene Diimide Trimer
Cyano groups have been widely used in polymeric donor materials and acceptor–donor–acceptor (A–D–A)-type nonfullerene acceptors. However, they have not yet been introduced into PDI-based materials. To fill this research gap, we synthesized a ring-fused cyanated PDI trimer as the nonfullerene acceptors in organic sola...
