From: Hyperfluorescence circularly polarized OLEDs consisting of chiral TADF sensitizers and achiral multi-resonance emitters

Fig. 4

Device configurations of (a) blue and (b) green HF CP-OLEDs and (c) molecular structures of v-DABNA and BN2. d Absorption spectra of v-DABNA and BN2 and PL spectra of (R)-OBN-XT-SXAC and (R)-OBN-XT-SFAC in toluene solutions (concentration: 1.0 × 10−5 M). e EL spectra, (f) luminance–voltage–current density curves, (g) external quantum efficiency–luminance curves, and (h, i) CP-EL spectra and plots of gEL versus EL wavelength of blue (device (R)-HF1) and green (device (R)-HF2) co-phase sensitized HF CP-OLEDs using (R)-OBN-XT-SXAC and (R)-OBN-XT-SFAC as sensitizers and v-DABNA and BN2 as emitters. Inserts in plane (e): photos of blue and green HF CP-OLEDs.
