Abstract: A compound having a formula M(LA)x(LB)y(LC)z is provided. In the compound of M(LA)x(LB)y(LC)z, ligand LA is ligand LB is and ligand LC is In addition, M is a metal having an atomic mass greater than 40, x is 1, 2, or 3, and y and z are independently 0, 1, or 2. In the compound, Z5 is carbon or nitrogen; one of Z1 to Z4 is nitrogen and three of Z1 to Z4 are carbon substituted by RB, and rings C and D are each independently a 5 or 6-membered carbocyclic or heterocyclic ring. Each RA, RB, RC, and RD is independently selected from a group of substituents, where at least one RB is heteroaryl, which can be further substituted, and any adjacent substitutents are optionally joined or fused into a ring. Formulations and devices, such as OLEDs, that include the first compound are also provided.
