Circularly polarized electroluminescence (CP-EL) has drawn extensive attention owing to its direct asymmetrical emission of left-or right-hand circularly polarized light, which has diverse applications in frontier high-tech fields such as 3D display, quantum computing, and so forth . To realize CP-EL, developing efficient light-emitting materials with circularly polarized luminescence (CPL) for the fabrication of organic light-emitting diodes (OLEDs) is of high importance . Generally, CP-EL with a defined color is acquired from corresponding CPL materials with similar colors, which means a great number of CPL materials are required in OLEDs to fulfill the need of CP-EL in varied color regions . Currently, great efforts have been devoted to explore numerous new CPL materials to meet such kind of many-to-many relationship . These CPL materials are basically built by introducing chiral groups to molecular frameworks responsible for light emission via chiral perturbation, or constructing a chiral center directly in a rigid luminescent framework . These approaches often involve complicated synthetic procedures, but the CP-EL efficiencies of the resultant materials are not always satisfactory. Actually, a library of high-performance achiral EL materials, such as phosphorescence and thermally activated delayed fluorescence (TADF) materials, have been well-developed, and many of them have been commercialized, but they are rarely considered to be capable of direct producing CP-EL in previous researches.
