Claim 0:
1. A compound that is a metal coordination complex having a metal-carbon bond, wherein the compound is capable of functioning as a phosphorescent emitter in an organic light emitting device at room temperature;
wherein the compound has the formula Ir(L1)2(L2);
wherein L1 is a ligand LA selected from the group consisting of:, wherein G is selected from the group consisting of:, wherein in LA type1, X is C, R1 is R and R2 is CD3;
wherein in LA type2, R1, R2, and R4 are H and R3 is R;
wherein R is the structure of is-of Formula I, wherein R1 and R5 are H or deuterium;
wherein two of R2 to R4are methyl and the remaining one of R2 to R4 is tert-butyl; and
wherein when L1is LA type1, L2, wherein each Y1 to Y4 and Y6 to Y10 are carbon:
wherein Y5 is carbon or nitrogen;
wherein Y1 is O,
wherein Ra represents mono substitution, di substitution, or no substitution;
wherein Rb represents mono substitution to the maximum possible number of substitutions, or no substitution;
wherein Rc is hyrdrogen;
wherein each Ra is independently hydrogen or a substituent selected from the group consisting of CD3, deuterated neopentyl, and deuterated dimethylcyclohexane;
wherein each Rb is independently hydrogen or a substituent selected from the group consisting of CD3, alkenyl, and unsubstituted phenyl;
wherein if at least one Rb is alkenyl, the alkenyl joins with an adjacent second alkenyl to form an unsubstituted phenyl;
wherein if Rb is unsubstituted phenyl, the unsubstituted phenyl joins with an adjacent first alkenyl to form an unsubstituted naphthalene;
wherein when L1 is LA type2, L2is, wherein Rb is hydrogen and each Rx and Rz, is 3-pentyl.
