Abstract

Highly efficient red phosphorescent dopants in organic light-emitting devices have been explored by using a cyclometalated iridium complex with a fully methylated phenyl ring and a quinoline ring as well as a sterically crowded ancillary ligand. The red phosphorescent devices with these dopants give extremely high external quantum efficiencies.
