Aggregation‐induced emission polymer systems with circularly polarized luminescence

Functional materials with circularly polarized luminescence (CPL) have attracted tremendous attention due to their promising applications in three-dimensional displays, chiral recognition and catalysis, photoelectronic devices, contrast imaging, information encryption, other fields. Among various CPL-active materials, polymeric systems aggregation-induced emission (AIE) emerged as excellent candidates because of efficient aggregate-state fluorescence, large solid-state dissymmetry factor, processibility, diversified self-assembly behaviors, readily switchable CPL properties. This review summarizes discusses the recent progress well future perspective diverse AIE polymer CPL, including covalent polymers, supramolecular AIEgen/polymer composites CPL. According location or introduction method AIEgen structures, this further divides polymers into three categories, main chains, side clusterization-triggered emission. are discussed based on driving force for formation host–guest interactions, metal coordination, non-covalent interactions. Moreover, examples construction by physically mixing AIEgens (supra)polymers also presented. is anticipated provide readers an overall view design strategies facilitate research development advanced applications.
