    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： Provided are compounds comprising a first ligand LA which comprises a first B atom and a first N atom; the first B atom forms exactly three single bonds to three atoms selected from the group consisting of C and N; and one of the three atoms is the first N atom; the first N atom is a ring atom of a first 6-membered ring, and B is not a ring atom of the first 6-membered ring; the first 6-membered ring comprises at least two double bonds in at least one Lewis structural drawing; LA is coordinated to a metal M selected from the group consisting of Os, Ir, Pd, Pt, Cu, Ag, and Au; and LA may be joined with other ligands to comprise a bidentate, tridentate, tetradentate, pentadentate, or hexadentate ligand. Also provided are formulations comprising these compounds and OLEDs and related consumer products that utilize these compounds.
