Abstract
Emissive phosphorescent organometallic compounds that produce electroluminescence and organic light emitting devices employing such emissive phosphorescent organometallic compounds are provided. More specifically the present invention is directed to novel primarily non-emitting ligands which produce a blue shift in emitted light when associated with a cyclometallated ligand.
