Two new deep-blue narrowband multi-resonant emitters, 1B-DTACrs and 2B-DTACrs, based on boron, nitrogen, and oxygen doped nanographenes are reported, with one of them showing thermally activated delayed fluorescence (TADF). Devices based on 2B-DTACrs demonstrated a high EQE(max) of 14.8% and CIE coordinates of (0.150, 0.044), which closely meet the BT.2020 requirement for blue pixels.
