摘要

Circularly polarized luminescence (CPL) materials have garnered significant attention due to their diverse applications in fields, such as information encryption, three-dimensional displays, biological imaging, and optoelectronic devices. A crucial challenge in this domain is achieving a high luminescence asymmetry factor (|glum|), which quantifies the polarization efficiency of emitted light. This review systematically examines the latest developments in the CPL activity of small organic molecules, supramolecular assemblies, liquid crystals, and organic-inorganic perovskites. It introduces key strategies to enhance |glum| through macrocontrol measures, such as chiral nano-templates, energy transfer, hierarchical self-assembly, and external stimuli, as well as innovative molecular design approaches, including boron/nitrogen-doped frameworks and axial chiral frameworks. Additionally, it provides a comprehensive analysis of the correlation between material structure and polarization luminescence properties. The purpose is to enable readers to understand circular polarization and methods to increase the |glum|.
