摘要：

Two kinds of chiral hosts, named (R/S)-BN-mCP and (R/S)-BN-2mCP, are prepared. Solution processable circularly polarized organic light-emitting diodes (CP-OLEDs) based on the chiral hosts and achiral emitter Ir(mypp)(3) present the maximum external quantum efficiency (EQE(max)) and dissymmetry factor values (g(EL)) of 12.7%/-1.7 x 10(-3) and 17.1%/-1.3 x 10(-3), respectively. Using (R)-BN-2mCP as the chiral host and Ir(mypp)(3) and Ir(piq)(2)(acac) as the achiral emitters, the solution-processed OLED exhibits a broad emission spectrum with the EQE(max) of 12.1% and g(EL) of -1.1 x 10(-3).
