A spiro compound DPAA-AF combining an electron-accepting diazafluorene unit and an electron-donating bis(diphenylamino)acridane unit has been synthesized and used as an emitter in organic light-emitting diodes. DPAA-AF exhibits efficient thermally activated delayed fluorescence, and a device based on this compound emits blue-greenish electroluminescence with a maximum external quantum efficiency of 9.6%.
