Claims20
A compound comprising a ligand LA of Formula I:
- wherein:
- moiety A and moiety B are each independently monocyclic or polycyclic ring structure containing 5-membered and/or 6-membered carbocyclic or heterocyclic rings;
- each of Z1-Z4 is independently C or N, with at least one of Z3 and Z4 being C;
- K1, and K2, are each independently a direct bond, O, or S;
- each of X1-X7 is independently C or N, with at least one of X3 or X7 being N;
- represents a single bond or a double bond;
- the two wavy lines indicate linkage points to two adjacent ring carbon atom of moiety B;
- each of RA, RB, and RC represents zero, mono, or up to the maximum allowed number of substitutions to its associated ring;
- each RA, RB, and RC is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, germyl, boryl, selenyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- and
- any two adjacent RA, RB, or RC can be joined or fused to form a ring,
- wherein the ligand LA coordinates to M through the two indicated dashed lines;
- wherein M is selected from the group consisting of Os, Ir, Pd, Pt, Cu, Ag, and Au;
- and
- wherein the ligand LA can be joined with other ligands to form a tridentate, tetradentate, pentadentate, or hexadentate ligand.
