    Abstract: A compound comprising a first ligand LA of Formula I or Formula II: wherein A1 and A2 are each independently C or Si; wherein each RA, and RB independently represents mono to the maximum allowable substitution, or no substitution; wherein each X1, X2, and X3 is independently C or N; wherein each R, R1, R2, R3, R4 and RA is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, boryl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein LA is complexed to a metal M; wherein M is optionally coordinated to one or more other ligands; wherein the ligand LA is optionally linked with the one or more other ligands to form a tridentate, tetradentate, pentadentate, or hexadentate ligand; and wherein any two substituents are optionally joined or fused together to form a ring.

    Abstract: A compound comprising a ligand LA of Formulae I, II, or III wherein the ligand LA is coordinated to a transition metal M, and optionally, M is also coordinated to a ligand LB; A is N, B, or CR7; Y is absent, or selected from the group consisting of C(O), C(Rya)(Ryb), C═C(Rya)(Ryb), and Si(Rya)(Ryb), where if Y of Ring A is absent then ring carbon of R2 is bonded to N; wherein for the compounds of formula III at least one of R2, R3, and R4 is selected from N(Ar1)RN′ or aryloxy; wherein Ar1 is selected from aryl or heteroaryl, each of which is optionally substituted. An OLED that includes an organic layer disposed between an anode and a cathode, and the organic layer includes a compound comprising a ligand LA of Formulae I, II, or III above. The OLED can be incorporated into one or more of a consumer product, e.g., an electronic component module, a flat panel display, e.g., a display for a phone, television, laptop, and/or a lighting panel for either commercial or residential applications.
