A compound comprising a first ligand LA of Formula I:
- Formula I;
- wherein ring B is a 5 or 6-membered carbocyclic or heterocyclic ring;
- wherein RA represents from disubstitution to the possible maximum number of substitution;
- wherein RB represents monosubstitution to the possible maximum number of substitution, or no substitution;
- wherein ZA and ZB are each independently selected from the group consisting of carbon or nitrogen;
- wherein at least two adjacent RA are joined and fused to ring A and have the following formula:
- wherein A1, A2, A3, and A4 are each independently CR or N;
- each R can be the same or different;
- wherein Z1 and Z2 are each independently selected from the group consisting of O, S, Se, NR′, CR′R″, and SiR′R″;
- wherein the ring containing Z1 and Z2 is a non-aromatic ring;
- wherein R, R′, R″, RA, and RB are each independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
- wherein any adjacent substituents are optionally joined or fused into a ring;
- wherein the ligand LA is coordinated to a metal M;
- wherein the metal M can be coordinated to other ligands;
- and
- wherein the ligand LA is optionally linked with other ligands to form a tridentate, tetradentate, pentadentate or hexadentate ligand.
