Circularly polarized thermally activated delayed fluorescence (CP-TADF) materials have the characteristics of easily modified molecular structure, high exciton utilization and circularly polarized luminescence, which are the promising luminescent materials for the application of optical information storage, 3D displays, light-emitting devices and data encryption. The circular-polarized organic light-emitting diodes (CP-OLED) prepared by using such materials as emitting layers can simultaneously achieve high luminescence dissymmetry factor and theoretical 100% exciton utilization, which is crucial for the development of low-power and high-performance OLED. Recently, through the design and optimization of molecular structure, electroluminescence efficiency of CP-TADF materials were improved, but the problems of low luminescence dissymmetry factor and serious efficiency roll-off still existed. On this basis, the reported CP-TADF materials is reviewed and the relationship between the design strategies of molecular structure and the characters of excellent photophysical properties, circular polarization properties and electroluminescent properties is summaried. Furthermore, the preparation of high-perfor- mance of CP-TADF materials and their applications in OLEDs are prospected.

Key words: chiral organic luminescent material, circularly polarized light, thermally activated delayed fluorescence, organic light-emitting diode
