Claims19
A compound having the formula [LA]3-nIr[LB]n, having the structure:
- wherein R1, R2, R3, R4, and R5 each 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′, 0, S, Se, C═O, S═O, SO2, CR′R″, SiR′R″, and GeR′R″;
- wherein R′, R″, R′, R2, R3, R4, and R5 are 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 substitutions are optionally joined or fused into a ring;
- wherein n is 1 or 2;
- wherein R is selected from the group consisting of alkyl, and partially or fully deuterated variants thereof;
- and
- wherein R has at least five carbon atoms.
