    Abstract: A compound having the structure of Formula I is disclosed. In the structure of Formula I, each of R1, R2, and R3 is independently a hydrogen, a non-fused aryl group having one meta-substituent, or a non-fused heteroaryl six-membered ring having one or more meta-substituents; each meta-substituent is a non-fused aryl or non-fused heteroaryl six-membered ring optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups; and at least one of R1, R2, and R3 is a non-fused aryl having one meta-substituent or a heteroaryl six-membered ring having at least one meta-substituent, wherein each meta-substituent is a non-fused aryl or non-fused heteroaryl group further substituted with a chain of at least two non-fused aryl or non-fused heteroaryl groups. The compounds may be useful in phosphorescent organic light emitting devices.

    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.
