    Abstract: A compound of Formula I or Formula II wherein Y is selected from the group consisting of O, S, and NRN; and (a) L1 and L2 are the same or different and are each a mono-anionic bidentate ligand; and R is selected from the group consisting of hydrogen, deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; or (b) R joins with L1 of the Formulae I or II to form a ring B1 of formula B and formula C, respectively, and L2 is L3 and L3 is a tridentate ligand of formula D wherein ring C, ring D, and ring E are each independently selected from the group consisting a 5-membered aryl, a 5-membered heteroaryl, a 6-membered aryl, and a 6-membered heteroaryl; X1 to X4 are independently selected from C or N, and no more than two of the X1 to X4 is N; Z1 to Z7 are independently selected from C or N; wherein one of Z1, Z4, and Z7 is an anionic donor, and the remaining two are neutral donors; wherein Z2 and Z3 are not both N, and Z5 and Z6 are not both N; and the dotted lines represent coordination to the iridium; wherein each RA to RE represents mono to the maximum allowable substitution, or no substitution; and each RA to RE is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof, wherein any two adjacent substituents RA to RE are optionally joined to form a fused ring.

    Abstract: A compound having a structure of Formula I, is provided. In Formula I, two of Z1, Z2, Z3, and Z4 are C and the other two are N; each of X1 to X16 is independently C or N; each of L1 and L2 is independently a direct bond or a linker; one of L1 and L2 is present; M is Pd or Pt; each RA, RB, RC, and RD is independently hydrogen or a substitutent selected from the General Substituent; and any two of RA, RB, RC, and RD can be joined or fused together to form a ring. Formulations, OLEDs, and consumer products including the compound of Formula I are also disclosed.
