triplet states while maintaining frontier molecular orbital levels, and thereby optimizing their optoelectronicproperties. Employing these TADFemitters results in a green fluorescent organic light‐emittingdiode (OLED) that exhibits a peak forward‐viewing externalquantumefficiency (EQE) close to 25 % and a slowefficiency roll‐off characteristic at high luminance.
