The dibenzothiophene derivative, 2,8‐bis(9,9‐dimethylacridin‐10(9H)‐yl)dibenzothiophene 5,5‐dioxide, as synthesized as a thermally activated delayed fluorescence material for green fluorescence organic light‐emitting diodes. The dibenzothiophene derivative had a donor‐acceptor structure for thermally activated delayed fluorescent emission and high maximum quantum efficiency of 14.3% was achieved in green devices.
