Abstract:
A compound having the formula (LA)mIr(LB)3-m, where LA is
and LB is selected from
is disclosed. In the formula (LA)mIr(LB)3-m, LA and LB are different; each of X1 to X5 is C—RF or nitrogen; X is selected from O, S, and Se; each R1, R2, RB, RD, RE, and RF is hydrogen or a substituent; R3 is alkyl, cycloalkyl, or a combination thereof; and m is 1 or 2. OLEDs, consumer products, and formulations including the compound are also disclosed.
