    Abstract: A compound comprising a ligand LA of Formula I coordinated to a metal M as represented by the dotted lines wherein ring A is a 5-membered or 6-membered carbocyclic or heterocyclic ring, and ring B is a multicyclic ring system comprising four to eight fused 5-membered or 6-membered, carbocyclic or heterocyclic rings; wherein the ring B includes a structure of Formula II wherein ring C is a 5-membered or 6-membered carbocyclic or heterocyclic ring, and the dotted lines of Formula II represent fusion of the structure of Formula II as part of the multicyclic ring system of ring B; T1, T2, and T3 are independently selected from N or C; and L is a linker L2-L1 with L2 and L1 independently selected from the group consisting of O, S, NRN, CR1R2, CR3R4, SiR1R2, and SiR3R4; wherein at least one of L1 or L2 is CR1CR2 or SiR1R2; and the metal M is selected from the group consisting of Ir, Rh, Re, Ru, Os, Pt, Pd, Au, and Cu. An OLED that includes an organic layer, and the organic layer comprises a compound of Formula I above. An OLED that includes an organic layer including a compound with a ligand LA of Formula I, and a consumer product with an OLED.
