PHOSPHORUS CONTAINING BIS(TRIDENATE) OSMIUM COMPLEXES

摘要

Bis(tridentate) osmium(II) complexes containing phosphite groups useful as phosphorescent emitters are disclosed. The disclosed osmium(II) complexes have higher oxidation potential then previously known osmium(II) complexes. An organic light emitting device having an organic layer that includes the disclosed osmium(II) complex is also disclosed.
