Recent developments of di-amide/imide-containing small molecular non-fullerene acceptors for organic solar cells

摘要

Non-fullerene organic solar cells have received increasing attentions in these years,and great progresses have been made since 2013.Among them,aromatic di-amide/imide-containing frameworks have shown promising applications.The outstanding properties of them are highly associated with their unique electronic and structural features,such as strong electron-withdrawing nature,broad absorption in UVvisible region,tunable HOMO/LUMO energy levels,easy modifications,and excellent chemical,thermal and photochemical stabilities.In this review,we give an overview of recent developments of aromatic diamide/imide-containing small molecules used as electron acceptors for organic solar cells.
