    Abstract: Embodiments of the disclosed subject matter provide an apparatus having a device with a micronozzle array disposed on a micro-fabricated fluidic die. The device may include a first gas distribution plate and a second opposing plate, where the micro-fabricated fluidic die is disposed between the first gas distribution plate and the second opposing plate, wherein the first gas distribution plate is irreversibly joined to the micronozzle array with a seal that is gas-tight, and where the first gas distribution plate includes a plurality of sealed flow paths. A manifold may be reversibly joined to the first gas distribution plate, where the micro-fabricated fluidic die and the first gas distribution plate and the second opposing plate are disposed between the manifold. A thermally conductive plate may have at least one window that provides a clearance fit for the device across a range of motion relative to the thermally conductive plate.

    Abstract: A compound having a first ligand LA of Formula I, is disclosed. In the structure of Formula I, Z1 through Z7 are each independently C or N; ring B is a 5-membered or 6-membered ring; each RA, RB, and RC is independently hydrogen or one of a variety of substituents; any two substituents in RC may be joined or fused together to form a ring. In the compound, LA is complexed to a metal M, which is optionally coordinated to other ligands. In addition, ligand LA is optionally linked with other ligands to comprise a tridentate, tetradentate, pentadentate, or hexadentate ligand. Organic light emitting devices, consumer products, formulations, and chemical structures containing the compounds are also disclosed.

    Abstract: A compound including ligand LA of Formula I, where LA includes at least one deuterium atom is provided. In Formula I, moiety A and B are monocyclic rings or polycyclic fused rings; K1 and K2 are direct bond, O, or S; and either (1) two RA or two RB substituents are joined together to form a fused ring structure of Formula II, where Formula II is joined to ring A or ring B, respectively, by the dashed lines, and Y is Se or GeR′R″; or (2) at least one RA or RB comprises a structure of Formula III, and Y is Se or GeR′R″; where Formula III is not fused to either of ring A or ring B. Formulations, OLEDs, and consumer products including the compound are also provided.
