A series of pyrimidine‐conjugated thermally activated delayed fluorescent (TADF) emitters is developed. Using a highly emissive green pyrimidine conjugate emitter and sophisticated device engineering, the optimized device operates on 2.2 V at 1 cd m −2 and exhibits a superior performance with an η ext of over 25%, an η p of over 110 lm W −1 , and exceptionally low efficiency roll‐off.
