Provided is a compound comprising a first ligand LA of
Claims20
A compound comprising a first ligand LA of
- wherein,
- each X1 to X10 is C or N;
- the maximum number of X1 to X10 that are in the same ring as N is three;
- RA and RB each represent mono to the maximum allowable substitution, or no substitution;
- LA is complexed to a metal M;
- each RA and RB is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, boryl, and combinations thereof;
- M can be coordinated to other ligands;
- the ligand LA can be linked with other ligands to comprise a tridentate, tetradentate, pentadentate, or hexadentate ligand;
- and
- any two substituents can be joined or fused together to form a ring.
