    Abstract: Embodiments of the disclosed subject matter provide a vapor distribution manifold that ejects organic vapor laden gas into a chamber and withdraws chamber gas, where vapor ejected from the manifold is incident on, and condenses onto, a deposition surface within the chamber that moves relative to one or more print heads in a direction orthogonal to a platen normal and a linear extent of the manifold. The volumetric flow of gas withdrawn by the manifold from the chamber may be greater than the volumetric flow of gas injected into the chamber by the manifold. The net outflow of gas from the chamber through the manifold may prevent organic vapor from diffusing beyond the extent of the gap between the manifold and deposition surface. The manifold may be configured so that long axes of delivery and exhaust apertures are perpendicular to a print direction.

    Abstract: A compound having a Pt tetradentate structure of Formula I, is disclosed. In Formula I, rings A, B, and C each independently represent a 5- or 6-membered carbocyclic or heterocyclic ring; L1, L2, and L3 are each independently selected from the group consisting of a direct bond, BR, NR, PR, O, S, Se, C═O, S═O, SO2, SiRR′, GeRR′, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; X1, X2, and X3 are either carbon or nitrogen; X is O, S, or Se; R1, R2, R3, RA, RB, RC, R, and R′ are each independently selected from H and a variety of substituents; and any adjacent R1, R2, R3, RA, RB, RC, R, and R′ are optionally joined to form a ring. Formulations and devices, such as OLEDs, that include the compound of Formula I are also described.
