    Abstract: A compound of Formula Ir(LA)(LB)(LC) is disclosed. In Formula Ir(LA)(LB)(LC), LA has Formula I, LB has Formula II, LC is a monoanionic bidentate ligand that does not comprise a phenylpyridine ligand; and each of LA, LB, and LC is different. Each of moieties A, C, and D is independently a monocyclic ring or a polycyclic fused ring structure or 5-membered and/or 6-membered rings; each of X1 to X6 is C or N; each of Z1 and Z2 is C or N; at least one of Z1 and Z2 is N; each RA, RB, RC, and RD is independently a hydrogen or a General Substituent; and any two adjacent substituents can be joined or fused together to form a ring. Formulations, OLEDs, and consumer products including the compound are also disclosed.
