    摘要: Heteroleptic cyclometallated complexes having a 6-membered ring cyclometallated to the metal, as shown in Formula (I), are provided: wherein ring A and ring B are each independently a 5 or 6-membered carbocyclic or heterocyclic ring; wherein L1 is BR, NR, PR, O, S, Se, C═O, S═O, SO2, CRR′, SiRR′, or GeRR′; wherein Z1 and Z2 are independently carbon or nitrogen; wherein at least one of Z1 and Z2 is carbon; wherein is a bidentate ligand selected from the group consisting of: wherein R1, R2, Ra, Rb, Rc, and Rd may represent mono, di, tri, or tetra substitution, or no substitution; wherein R1, R2, R, R′, Ra, Rb, Rc, and Rd are each independently selected from various substituents; and wherein n is 1 or 2. Devices, such as organic light emitting devices (OLEDs) that comprise phosphorescent light emitting materials are also provided.
