Abstract: A compound including a first ligand LA of Formula I, is disclosed. In Formula I, ring B is a 5- or 6-membered ring; X1, X2, and X3 are each CRA or N; R is a 5- or 6-membered carbocyclic or heterocyclic ring, which can be further fused or substituted; and (1) when ring B is an unfused 6-membered ring, X1 and X2 are N, and X3 is C; and (2) when ring B is a fused 6-membered ring, ring B has the structure of Formula II, In this structure, the wavy line indicates the point of connection to ring A; Q1 to Q6 are each C or N; and, when proviso (2) applies, (I) at least one of X1, X2, and X3 is N; or (II) R is two or more fused or unfused 5- or 6-membered carbocyclic or heterocyclic rings, or (III) at least ring A or R is substituted with a partially or fully deuterated alkyl or partially or fully deuterated cycloalkyl group.
