    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.
