Circularly polarized organic light-emitting diodes (OLEDs) own the capability to directly radiate left-or right-hand circularly polarized electroluminescence (CP-EL), and have attracted increasing attention in 3D display and quantum computing, among other applications . These OLEDs can be made into flexible, ultrathin and transparent patterns, becoming a promising technique for high-tech devices . The conventional approach for fabricating circularly polarized OLEDs mainly focuses on the design and synthesis of efficient organic materials with circularly polarized luminescence, which are subsequently utilized as the emitting centers in light-emitting layers (EMLs) . Alternatively, circularly polarized OLEDs can also be obtained based on chirality-induction strategy of blending a chirality inducer with emitting materials during the preparation of the EMLs . Essentially, the chiral nature of these devices originates from the chiral emitting materials or the chiral environments in EMLs . In general, once multiple emission colors are required, such as in circularly polarized white OLEDs, various efficient chiral emitting materials and well-matched chiral hosts are needed, which sets high and complicated requirements for both chiral emitters and hosts .
