Circularly polarized luminescence (CPL) materials possess the unique ability to directly emit circularly polarized light with a specific handedness. These materials hold significant promise for application in cutting-edge technological domains, including 3D displays, chiral photocatalysis, optical sensing, tunable lasers, as well as information storage and encryption. Consequently, they have emerged as a focal point of research within the fields of chiral photonics and advanced optical materials. Nevertheless, a pivotal challenge in this area remains the preparation of CPL materials with a high luminescence dissymmetry factor (glum). The cholesteric liquid crystal (CLC) assembly system, characterized by its distinctive periodic helical superstructure and exceptional self-assembly capabilities, offers a novel pathway to address this challenge.
