Blue‐Emitting Heteroleptic Iridium(III) Complexes Suitable for High‐Efficiency Phosphorescent OLEDs

Abstract

Dyed-in-the-wool true blue: True-blue phosphorescent organic light-emitting diodes are fabricated by using an IrIII dopant (see picture; gray C; blue N; red Ir; green F). The Ir complex has an enhanced metal-to-ligand charge-transfer contribution, hence a shortened radiative lifetime in the excited state. The maximum external quantum efficiency of the fabricated device is 8.5 % and the main emission is around 450 nm.
