Circularly polarized luminescence (CPL) materials have attracted significant research interest in recent years due to their promising applications in areas such as 3D displays, etc. Among various material systems, small organic molecules have emerged as a pivotal platform for constructing CPL-active materials, owing to their well-defined structure-property relationships. Meanwhile, room-temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) materials can effectively utilize triplet excitons, while aggregation-induced emission (AIE) materials suppress the aggregation-caused quenching (ACQ) common to traditional fluorophores. Consequently, the integration of RTP, TADF, and AIE functionalities into CPL materials has not only substantially enhanced their optical and device performance but also significantly broadened their application scope. This article begins with a brief introduction to CPL small organic molecules, then focuses on the design strategies, optical properties, and device performance of such multifunctional CPL systems. Finally, it concludes by summarizing the current challenges and future research directions in this field.

Key words: circularly polarized luminescence, room-temperature phosphorescence, thermally activated delayed fluorescence, aggregation-induced emission, small organic molecules
