Claims16
A compound having the structure of (LA)nIr(LB)3-n represented by Formula I:
- wherein R2, R3, R4 and R5 each represent monosubstitution, disubstitution, trisubstitution, tetrasubstitution, or no substitution;
- wherein R1 is an aryl or heteroaryl comprising at least one group selected from group A consisting of:
- wherein R1 can be further substituted with one or more substituents selected from the group consisting of deuterium, halide, alkyl, cycloalkyl, and combinations thereof;
- wherein R2, R3, R4, and R5 are each independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, and combinations thereof;
- and
- wherein n is 1 or 2.
