Abstract: Compounds are provided that comprise a ligand having a 5-substituted 2-phenylquinoline. In particular, the 2-phenylquinoline may be substituted with a cycloalkyl containing group at the 5-position. These compounds may be used in organic light emitting devices, in particular as red emitters in the emissive layer of such devices, to provide devices having improved properties.
