Perylene-3,4-(dicarboxylic monoimide)-9,10-(dicarboxylic monoanhydrate)(PIA)is one key intermediate to construct functionalized perylene diimides(PDIs)for various applications.However,the difficulty in synthesizing chlorinated PIA hinders the study of chlorinated PDIbased materials.Although chlorination has been widely used to modify the properties of organic semiconductors.We successfully synthesize chlorinated PIA via a simple hydrolysis reaction using LiOH as the base,then a PDI dimer connected at the imide position,N-di-PDI-4Cl,is synthesized as an application example of chlorinated PIA.The heavily chlorinated PDI dimer exhibits deeper energy levels,slightly blue-shifted UV-Vis absorption compared to the non-chlorinated analogue.In addition,the photovoltaic performance of N-di-PDI-4Cl is characterized.This study paves one easy way to synthesize chlorinated PIA and its more delicate derivatives. 展开更多
