Fig. 5: Deep-blue fluorescent OLED device with TDBA-pyCz and DPAc-Cz developed by DL-assisted virtual screening.

a Molecular structures of DPAc-Cz (host) and TDBA-pyCz (emitter). b Device structure. c CIE 1931 chromaticity diagram. d Current density (J)–Voltage (V)–Luminance (L) curves. e EQE–Luminance (L) curves. f EL spectra at different doping concentrations of emitters at a luminance of 500 cd m−2. A photograph of the device emission is shown in the inset.
