    摘要： A compound including a bidentate ligand LA comprising a structure of Formula I, is disclosed. In Formula I, ring A′ is a 7-, 8-, or 9-membered ring structure; X is of NR2, O, CR, CRR′, S, or SiRR′; each of RA′, R1, and R2 is independently hydrogen or a substituent; R1′ is independently absent or a hydrogen or a substituent; any two adjacent RA′, R1, R1′, and R2 can be joined or fused to form a ring; the ligand LA is coordinated to a metal, which is selected from Os, Ir, Pd, Pt, Cu, Ag, or Au; and (1) at least one of R1 and R2 is coordinated to the metal M, or (2) at least one RA′ comprises a 5- or 6-membered carbocyclic or heterocyclic ring that is not directly fused to Ring A′ and is coordinated to the metal M, or both (1) and (2) are true. Formulations, devices, and consumer products including the compound are also disclosed.

    摘要： A compound comprising a ligand LA of Formula I, is disclosed. In Formula I, each of Z1, Z2, Z3, Z4, Z5, and Z6 is C or N; K is selected from a direct bond, O, and S; if K is O or S, then Z6 is C; ligand LA is coordinated to a metal by the dash lines; M is coordinated to at least one other ligand; L1 is an organic linker; if M is selected from Ru, Os, or Ir, then K is O or S; if M is selected from Pt, Pd, Cu, Ag, or Au, and K is a direct bond, then M forms at least one bond to oxygen or sulfur; when M is selected from Pt, Pd, Cu, Ag, or Au, and K is O or S, then L1 is selected from —CR═N—, —CR′R″CR′R″—, —NR′BR′—, —CR′R″O—, —CR′R″S—, —CR′═CR″O—, —CR′═CR″S—, —CR′═CR′NR—, —CR′═CR″CR2—, —C(═N—)—, and —C(═CR—)—.

    摘要： A compound comprising a first ligand LA, where LA comprises a structure of Formula I, is provided. In Formula I, each of X1, X2, X3, and X4 represents CR, CRR′, NR, or N; Y is selected from a linking group; each of R, R′, R″, R1, R1′, R2, R2′, R3, R3′, R4, and R4′ is hydrogen or a substituent; each represents a single bond or a double bond; any two adjacent substituents may be joined or fused to form a ring; two adjacent ones of R1, R2, R3, and R4 are joined together to form a fused 5-membered heterocyclic ring, Ring A, while the remaining two of R1, R2, R3, and R4 cannot be joined to form an aromatic ring; and Ring A is joined to a metal M by a direct bond. Formulations, OLEDs, and consumer products comprising the compound are also provided.
