Recent Advances in Circularly Polarized Luminescence of Liquid Crystalline Aggregation‐Induced Emission Materials

Abstract Circularly polarized luminescence (CPL) materials have gained increasing attention for their potential in advanced photonic and chiroptical technologies. Among them, AIE‐CPL‐LC materials integrating aggregation‐induced emission (AIE) with liquid crystalline (LC) order represent a distinctive class of CPL materials. These materials not only exhibit strong emission in the condensed phase but also demonstrate efficient chirality transfer and a remarkable amplification effect of chiral signals. This review summarizes recent advances in the design, assembly, and functional modulation of AIE‐CPL‐LC materials. A key feature is the significant enhancement of luminescence dissymmetry factor ( g _lum ) achieved by the self‐assembled ordering of mesogens while maintaining strong AIE performance. This enhancement arises from the chiral amplification effect driven by the ordered mesogenic structures, which extend chiral organization from the nanoscale to mesoscopic or even macroscopic levels through helical superstructures. Such hierarchical chirality amplification enhances g _lum by orders of magnitude, thereby improving the CPL efficiency. The intrinsic asymmetry of chiral mesogenic structures may also contribute to CPL activity. Special emphasis is placed on elucidating structure‐property relationships, particularly the influence of mesophase type, molecular alignment, and external stimuli on g _lum and the photoluminescence quantum yield. AIE‐CPL‐LC materials offer a versatile and powerful foundation for the next‐generation chiral photonic devices development.
