a Configuration, energy levels and (b) chemical structures of functional layers of the doped devices based on (R/S)-OBN-XT-SXAC and (R/S)-OBN-XT-SFAC. EML is the doped film of 10, 20 and 30 wt% (R/S)-OBN-XT-SXAC or (R/S)-OBN-XT-SFAC in PPF host. c EL spectra, external quantum efficiency–luminance (The insert show the photo of the device with 20 wt% doping concentration) and (d) plots of luminance–voltage–current density of the OLEDs based on (R)-OBN-XT-SXAC. The doped OLEDs are fabricated with different (R)-OBN-XT-SXAC doping concentration in PPF host. e CP-EL spectra and (f) plots of gEL versus EL wavelength of doped OLEDs of (R/S)-OBN-XT-SXAC. The doping concentration is 20 wt%.
