Circularly polarized luminescence (CPL) not only can reflect the excited state structure information of chiral system, but also has wide potential applications in 3D display, communication of spin information, information storage and processing, CPL laser and biological probe. Consequently, more and more attention and interests have been attracted into this field, which turns to be one of the most hot topics in organic luminescence materials in recent years. In this review, recent progress on the chiral organic small molecules with CPL properties is summarized. First, CPL concept and earlier studies of CPL and organic small molecules with CPL properties are briefly introduced. Then, chiral organic small molecules with CPL properties are classified into four types of central chirality, axial chirality, planar chirality, and helical chirality, and their progresses in recent years are systematically described, respectively. Among the small molecular systems with different types of chirality, those ones based on the biaryl skeleton and helicene derivatives show excellent CPL properties, and they could also be controlled or switched by anions, protons and others. Moreover, it should be paid attention to the applications of aggregation induced effect (AIE) and supramolecular chemistry for the chiral organic small molecules to obtain better CPL property. Finally, a conclusion and perspective on CPL materials based on chiral small molecules is provided.
