    Abstract: A compound having a structure according Formula Ir(LA)n(LB)3−n: is described. In the structure of Formula Ir(LA)n(LB)3−n: A1, A2, A3, A4, A5, A6, A7, and A8 are each carbon or nitrogen; at least one of A1, A2, A3, A4, A5, A6, A7, and A8 is nitrogen; ring B is bonded to ring A through a C—C bond; the iridium is bonded to ring A through an Ir—C bond; X is O, S, or Se; R1, R2, R3, and R4 each independently represent no substitutions up to the maximum possible substitutions; any adjacent substitutions in R1, R2, R3, and R4 are optionally linked together to form a ring; each R1, R2, R3, R4, and R5 is independently selected from a variety of substituents; and n is an integer from 1 to 2. Formulations and devices, such as an OLEDs, that include the compound of Formula Ir(LA)n(LB)3−n are also described.

    Abstract: A compound comprising a first bidentate ligand LA, wherein LA comprises a structure of Formula I;






    wherein Z is selected from the group consisting of O, S, NR, BR, CRKRL, SiRKRL, —CRKRLCRMRN—, —SiRKRLSiRMRN—, —CRKRLO—, —SiRKRLO—, and —CRK═CRL—;
    wherein ring A, ring B, and ring C are each independently a 5-membered carbocyclic ring, 5-membered heterocyclic ring, 6-membered carbocyclic ring or 6-membered heterocyclic ring;
    wherein LA is coordinated to a metal M forming a 5-membered chelate ring;
    wherein M is selected from the group consisting of Ir, Pt, Pd, Ru, Rh, Os, Re, Cu, Ag, and Au;
    wherein RA, RB, and RC each represent mono to the maximum allowable substitution, or no substitution;
    wherein each R, RK, RL, RM, RN, RA, RB, and RC 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 M is optionally coordinated to one or more other ligands;
    wherein any two substituents are optionally joined or fused together to form a ring; and
    with the provision that LA does not comprise the following structure:

    Abstract: Heteroleptic iridium complexes having the formula are disclosed. In this formula, R1, R2, R3, R4, R5, and R6, are selected from hydrogen, deuterium, cycloalkyl, deuterated cycloalkyl, alkyl, and deuterated alkyl, and can optionally be linked together to form a ring; at least one of R1, R2, R3, R4, R5, and R6 is cycloalkyl, deuterated cycloalkyl, alkyl, or deuterated alkyl; ring A is attached to the 4- or 5-position of ring B; and R and R′ can represent any of a variety of subsitutents. These iridium compounds contain alkyl substituted phenylpyridine ligands, which provide these compounds with beneficial properties when the iridium complexes are incorporated into OLED devices.
