Purely organic circularly polarized luminescent (CPL) materials have attracted much attention owing to their fascinating photophysical properties and potential applications in the fields of optical data storage, smart sensors/probers, high‐resolution 3D display, and so on. With the development of photophysical science, the emergence of some novel emission phenomena, such as thermally activated delayed fluorescence (TADF) and room‐temperature phosphorescence (RTP), have become hot topics and enriched CPL materials. However, there is no systematic review that summarizes the recent development of chiral small organic molecules (SOMs) with TADF and RTP characters. In this minireview, the progress of purely organic CPL materials in the last 5 years is reviewed by categorizing into chiral fluorescence molecules, chiral TADF molecules, and chiral RTP molecules. Furthermore, the design strategy of chiral TADF emitters is discussed and the correlation between chirality and RTP properties is concluded.
