Successfully, unlike two-emitting-layer devices with single CP-EL signal from green BDMAC-XT layer, the three-emitting-layer device W1 display white CP-EL signals consisting of green and red CP-EL emissions from achiral BDMAC-XT and DBP, respectively, as well as deep-blue emission from chiral (S)-PCNTPA. Specifically, the EL spectrum of device W1 shows three EL peaks at 434 nm from (S)-PCNTPA layer, 510 nm from BDMAC-XT layer, and 610 nm from DBP layer, with a high color rendering index (CRI) of 92, and the good chromaticity coordinates are (0.321, 0.339), indicative of the high quality of the white light (Fig. , Supplementary Fig. ). Device W1 also exhibits excellent performance with a high ηext,max reaching 24.2% (Table ). More importantly, apparent CP-EL signals covering a wide region from 380 to 780 nm with |gEL| values of 0.47 × 10 -3 @ 434 nm, 3.51 × 10 -3 @510 nm and 1.90 × 10 -3 @610 nm are recorded, revealing both achiral green and red layers have been enabled to radiate CP-EL in device W1 (Supplementary Fig. and), indicating the CISS effect still works in multi-emitting-layer devices.
