Highly Efficient Red Phosphorescent Dopants in Organic Light-Emitting Devices

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...

Description
Summary: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.
