Abstract: The present invention relates to metal complexes having novel ligands. The compounds are useful in organic light emitting devices (OLEDs), particularly as emitting dopants. The incorporation of these novel ligands provides red phosphorescent materials with good external quantum efficiency, good color, and long lifetime.
