    摘要： A composition comprising a first compound capable of functioning as a phosphorescent emitter in an organic light emitting device at room temperature is provided. The first compound includes at least one substituent R, where each of the at least one substituent R has the formula of: - - -G1-G2, where the dashed line denotes the bond through which R is attached in the first compound; G1 is a non-aromatic cyclic or polycyclic group; G2 is selected from aryl and heteroaryl; and G1 and G2 are independently, optionally further substituted with a substituent 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. Organic light emitting devices, consumer products, and formulations containing the first compound are also provided.

    摘要： A compound having a Pt tetradentate structure of Formula 1, is provided. In the structure of Formula 1, rings C and D each independently represent 5- or 6-membered carbocyclic or heterocyclic ring; L1, L2, and L3 are each independently a direct bond, BR, NR, PR, O, S, Se, C═O, S═O, SO2, SiRR′, GeRR′, alkyl, cycloalkyl, or a combination thereof; the sum of n1 and n2 is 1 or 2; X is selected from NRE, O, S, and Se; X3 and X4 each independently carbon or nitrogen; and one of Q1, Q3, and Q4 is oxygen, and the remaining two of Q1, Q3, and Q4 each represents a direct bond. Formulations and devices, such as an OLEDs, that include the compound of Formula 1 are also described.
