Abstract
Highly efficient low‐voltage‐driven true‐blue thermally activated delayed fluorescence diodes are realized through employing a tri‐phosphine oxide host (2,2′,4‐tris(di(phenyl) phosphoryl)‐diphenylether (DPETPO)) with a record external quantum efficiency of 23.0% and the lowest onset voltage of 2.8 V to date.Keywords
