Claims20
A compound having the formula [LA]3-nIr[LB]n;
- wherein LA is
- wherein LB is
- wherein each R1, R2, R3, R4, R5, and R6 independently represents mono, to a maximum possible number of substitutions, or no substitution;
- wherein X is selected from the group consisting of BR, NR, PR, O, S, Se, C═O, S═O, SO2, CRR′, SiRR′, and GeRR′;
- wherein X1 to X6 are each independently carbon or nitrogen;
- wherein each R, R′, R1, R2, R3, R4, R5, and R6 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;
- wherein any adjacent R1 substitutions are optionally joined or fused into a ring;
- wherein any adjacent R2 substitutions are optionally joined or fused into a ring;
- wherein any adjacent R3 substitutions are optionally joined or fused into a ring;
- wherein any adjacent R4 substitutions are optionally joined or fused into a ring;
- wherein any adjacent R5 substitutions are optionally joined or fused into a ring;
- wherein any adjacent R6 substitutions are optionally joined or fused into a ring;
- and
- wherein n is 1 or 2.
