Circularly polarized luminescence from AIEgens

Abstract

Circularly polarized luminescence (CPL) based on aggregation-induced emission luminogens (AIEgens) has received increasing interest owing to the rise of applications to generate CPL devices and biologically active probes. CPL-active materials fabricated from AIEgens possess higher photoluminescence quantum yields and large dissymmetry factor in the solid state in comparison with single molecule in solution. This review highlights recent research in the CPL generation of AIEgens from (macro)molecular luminogens and supramolecular assemblies based on the AIE mechanism of restriction of intramolecular motion. In addition, some cases in which CPL-active AIEgens have enabled advancement in stimulus response materials and application in CPL devices, especially circularly polarized electroluminescence. Thus, CPL-active AIEgens are highly promising candidates for a wide range of technologically oriented multidisciplinary fields.
