摘要： A compound comprising a first ligand LA comprising a structure of Formula I,
is provided. In Formula I: moieties A and B are each a monocyclic ring or a polycyclic fused-ring system; each of Y1, Y2, Y3, and Y4 is independently a divalent, single atom long linker; each of L1 and L2 is independently a direct bond or a divalent, one atom ling linker; each RA, RB, or other substituent is hydrogen or a General Substituent defined herein; any two substituents may be joined or fused to form a ring; LA may be monodentate, bidentate, tridentate, tetradentate, pentadentate, or hexadentate; and LA is coordinated to a metal M and may be coordinated to other ligands. Formulations, OLEDs, and consumer products containing the compounds are also provided.-

摘要： A compound having a first ligand LA of Formula I,
is provided. In Formula I, Z is C or N; at least one of X1 to X5 is N, and the remainder are C; if X1 is N, then X5 is C; K is selected from the group consisting of a direct bond, O, S, N(Rα), P(Rα), B(Rα), C(Rα)(Rβ), and Si(Rα)(Rβ); each Rα, Rβ, RA and RB is a hydrogen or a General Substituent; LA is coordinated to a metal M; and Ring A coordinates to M through a metal carbene bond. Formulations, OLEDs, and consumer products containing the compound are also provided.-

摘要： A compound including a first bidentate ligand LA that includes a structure of Formula I, are provided. The ligand LA is coordinated to a metal M and can be joined with other ligands. In Formula I, in addition to some exclusions, each of X1, X2, X3, and X4 is C or N; two R1, R2, and R3 can be joined or fused to form a ring; and each R1, R2, and R3 is independently a group containing the metal M, a hydrogen, or a General Substituent defined herein. Formulations, OLEDs, and consumer products containing the compound are also provided.
