Abstract: A compound comprising a first ligand LA of Formula I,




is provided. In Formula I, moiety A and moiety B either a monocyclic ring or a polycyclic fused ring system; each of X1 to X4, Z1, and Z2 is C or N; K1 is a direct bond, O, S, N(Rα), P(Rα), B(Rα), C(Rα)(Rβ), or Si(Rα)(Rβ); L1 is a direct bond or a linking group; each Rα, Rβ, RA and RB is hydrogen or a General Substituent; and LA is coordinated to a metal M. In addition, RA or RB alone or in combination with a substituent of L1 form a 7-membered ring. Formulations, OLEDs, and consumer products containing the compound are also provided.
