摘　　要：In recent years,there has been a shift towards using non-fullerene electron acceptors in organic solar cells(osCs)as a replacement for fullerene derivatives.This change requires polymer donors that possess compatible physical properties,such as absorption range,HoMo energy level,miscibility,and crystallinity.Moreover,the high cost and poor batch-to-batch reproducibility of polymer donors also hinder future large-scale manufacturing.These emphasize the need to explore alternative types of polymer donors.The imide-functionalized building units possess several key attributes that make their polymers highly promising for non-fullerene OsCs.These attributes include ease of synthesis,strong electron-withdrawing ability,rigid and co-planar structure,and the ability to easily tune solubility through imide side chains.In this review,we summarized the synthetic routes of imide building units,and the structural evolution of imide-functionalized polymer donors by focusing on the effects of polymer structure on their physical,optoelectronic,and photovoltaic properties.We hope that this mini-review will serve as a catalyst for future research on imide-functionalized polymers toward high-performance,cost-effective,and durable organic solar cells(oscs).
