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.
