title: Design strategy for 25% external quantum efficiency in green and blue thermally activated delayed fluorescent devices.
abstract: Carbazole- and triazine-derived thermally activated delayed fluorescent (TADF) emitters, with three donor units and an even distribution of the highest occupied molecular orbital, achieve high external quantum efficiencies of above 25% in blue and green TADF devices.
