    摘要: Phosphorescent materials are provided, where the materials comprise a coordination compound having at least one ligand L3 having Formula (I): wherein A and B are each independently a 5-membered or 6-membered carbocyclic or heterocyclic ring; wherein RA, RB, RC, and RD each represent mono, di, tri, tetra substitutions, or no substitution; wherein Z1, Z2, Z3, Z4, Z5, Z6, Z7, and Z8 are each selected from N or C; wherein at least one of Z1, Z2, Z3, Z4, Z5, Z6, Z7, and Z8 is N; wherein one of Z1, Z2, Z3, and Z4 is C that is bonded to N of A; wherein Z is selected from the group consisting of BR, NR, PR, O, S, Se, C═O, S═O, SO2, CRR′, SiRR′, and GeRR′; wherein R, R′, RA, RB, RC, and RD are described herein; wherein L3 is coordinated to a metal M1; and wherein L3 may be linked with other ligands to comprise a tridentate, tetradentate, pentadentate, or hexadentate ligand. Devices, such as organic light emitting devices, comprising such compounds are also provided.
