Circularly polarized luminescence(CPL)materials have attracted considerable attention in recent years owing to their promising applications in 3D displays,information encryption,and bioimaging.The luminescence dissymmetry factor(glum)is a key parameter to evaluated CPL materials.Effectively enhancing glum is not only one of the core challenges but also a crucial prerequisite for advancing CPL technologies toward practical applications.Recent studies have demonstrated that a co-assembly strategy involving achiral polymers and chiral dopants can induce the formation of ordered helical supramolecular structures,thereby significantly amplifying CPL responses while enabling precise modulation of CPL properties without altering the polymer backbone.This review provides a systematic overview of recent advances in achiral-polymer-based co-assembled CPL materials.According to the chiral source,these systems are categorized into three types:co-assembly with chiral small molecules,co-assembly with chiral macromolecules,and co-assembly induced by chiral symmetry breaking.Particular emphasis is placed on their co-assembly mechanisms and structure-property relationships.In addition,this review outlines recent progress in the application of these materials in optoelectronic devices and discusses the major challenges currently faced in the field,as well as future development directions.This review aims to offer valuable insights and guidance for the rational design and development of next-generation high-performance CPL materials.
