    Abstract: A compound of the following Formula I is provided. In Formula I, A is C, B, Si, Ge, or Sn; each of X1 to X22 is independently C or N; Z1 and Z2 are each independently B or N; when A is B, one of X4, X5, X12, and X22 is N, and the remainder are C; when A is C, at least one of Z1 and Z2 is B; each of Y1, Y2, Y3, and Y4 is independently O, S, Se, NR, CRR′, SiRR′, GeRR′, and SnRR′; one of both of Y1 and Y2 are present; one of both of Y3 and Y4 are present; each R, R′, RA, RB, RC, RD, RE, and RF is independently hydrogen or a variety of substituents; and any two adjacent R, R′, RA, RB, RC, RD, RE, and RF can be joined or fused to form a ring. Devices, consumer products, and formulations including the compound are also disclosed.

    Abstract: A compound of Formula I






    wherein
    X1 and X2 are independently CRX or N, and at least one of X1 or X2 is CRX;
    Y is selected from the group consisting of O, S, Se, NR′, BR′, CR′R″, and SiR′R″;
    R′, and R″ are each independently selected from the group consisting of alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, aryl, heteroaryl, and combinations thereof;
    R is selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
    RA, and RC each independently represent mono to the maximum allowable substitution, or no substitution; and
    each RX, RA, and RC is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof, and wherein any two substituents RX, RA, and RC may be optionally joined to form a ring, with the proviso that R does not join with RA to form a ring.
