We report a family of thermally activated delayed fluorescence (TADF) dendrimers that exhibit both vanishingly small singlet-triplet gaps and large oscillator strengths. Host-free green solution-processed OLEDs show outstanding maximum external quantum efficiencies of up to 28.7%, current efficiencies of 98.8 cd A-1 and power efficiencies of 91.3 lm W-1.
