    Abstract: A compound having the structure of Formula I is disclosed. In the structure of Formula I, each of R1, R2, and R3 is independently a hydrogen, a non-fused aryl group having one meta-substituent, or a non-fused heteroaryl six-membered ring having one or more meta-substituents; each meta-substituent is a non-fused aryl or non-fused heteroaryl six-membered ring optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups; and at least one of R1, R2, and R3 is a non-fused aryl having one meta-substituent or a heteroaryl six-membered ring having at least one meta-substituent, wherein each meta-substituent is a non-fused aryl or non-fused heteroaryl group further substituted with a chain of at least two non-fused aryl or non-fused heteroaryl groups. The compounds may be useful in phosphorescent organic light emitting devices.

    Abstract: Compounds including a ligand L according to Formula I devices containing the same and formulations including the same are described. In Formula I, B is a 5 or 6-membered carbocyclic or heterocyclic ring; C is a condensed aromatic ring system having at least two carbocyclic or heterocyclic rings; A-B represents a bonded pair of carbocyclic or heterocyclic rings coordinated to a metal M via a nitrogen atom in ring A and an sp2 hybridized atom X6 in ring B; RA, RB and RC can represent no substitutions or the maximum substitutions available on the respective ring; X1, X2, X3, X4, X5, and X6 are carbon or nd nitrogen, and X7 is carbon; at least one of RA and RC substituents adjacent to the bond between A and C is not hydrogen; and the ligand is coordinated to a metal, having an atomic number greater than 40.

    Abstract: A compound having the structure of Formula 1, as well as, a first device and a formulation including the same are disclosed. In the structure of Formula 1: R5 is and (a) at least one of R1-R4 is or (b) R1 is In addition, R1, R2, R3, R4, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, Y1, Y2, Y3, Y4, Y5, Y6, Y7, Y8, Z1, Z2, Z3, Z4, Z5, Z6, Z7, and Z8, are each independently selected from a variety of substituents, where adjacent A, B, Y, and Z groups are, optionally, joined to form a fused ring structure. Finally, X includes an acceptor group selected from —CmF2m+1, —SimF2m+1, —NCO, —NCS, —OCN, —SCN, —OCmF2m+1, and —SCmF2m+1.
