wherein L 1 is selected from the group consisting of
wherein L 2 is a second ligand and L 3 is a third ligand and L 2 and L 3 can be the same or different;
wherein the second ligand L 2 and the third ligand L 3 are structure (a) independently selected from the group consisting of:
or structure (b) independently selected from the group consisting of
wherein x is 1 or 2;
wherein y is 1, or 2;
wherein z is 0 or 1;
wherein x+y+z is 3;
wherein each R a and R b is 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; and
wherein two adjacent substituents of R a and R b are optionally joined to form a fused ring or form a multidentate ligand.
