    Abstract: A compound including a first ligand LX of Formula II is disclosed, where F is a 5-membered or 6-membered carbocyclic or heterocyclic ring; each RF and RG independently represents mono to the maximum possible number of substitutions, or no substitution; Z3 and Z4 are each independently C or N and coordinated to a metal M to form a 5-membered chelate ring; G is a fused ring structure comprising five or more fused heterocyclic or carbocyclic rings, of which at least one ring is of Formula III the fused heterocyclic or carbocyclic rings in the fused ring structure G are 5-membered or 6-membered; of which if two or more 5-membered rings are present, at least two of the 5-membered rings are fused to one another; Y can be one of BR′, NR′, PR′, O, S, Se, C═O, S═O, SO2, CR′R″, SiR′R″, and GeR′R″; the metal M can be coordinated to other ligands; and the ligand LX can be linked with other ligands to comprise a tridentate, tetradentate, pentadentate, or hexadentate ligand.

    Abstract: A compound comprising a ligand LA coordinated to a metal M, the ligand LA selected from the group consisting of Formula I, Formula II, and Formula III ring A is a 5- or 6-membered carbocyclic or heterocyclic ring; wherein ring A of Formula I connects to ring B at X1, X2, or X3 to form a five-membered chelate ring with the metal; Z1 and Z2 are independently selected from C or N; and X1 to X10 are independently selected from C or N. An organic light emitting device (OLED) comprising an anode, a cathode and an organic layer disposed between the anode and the cathode, the organic layer comprising a compound selected from Formula I, Formula II, or Formula III, and a consumer product comprising the OLED.
