    Abstract: A compound of Formula I: wherein ring A is a 5-membered or 6-membered aromatic ring; wherein RA, RB, and RC each independently represent mono to the maximum allowable substitution, or no substitution; wherein Y1 is absent or present, and when present is selected from the group consisting of a direct bond, O, S, Se, CRR′, NR, SiRR′, and BR; wherein each X1-X3 is N or CR; wherein at least one of X1-X3 is N; wherein each A1-A5 is independently C or N; wherein the maximum number of N atoms that can connect to each other within each ring is two; wherein each R1, R2, R3, and R4 is independently selected from the group consisting of alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, aryl, heteroaryl, and combinations thereof; wherein each R, R′, RA, RB, 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 may be joined or fused together to form a ring.

    Abstract: A compound of Formula I: wherein Y is O, S, or Se; wherein each X1-X14 is independently C or N; wherein two consecutive X1-X14 in the same ring are not N; wherein any of X1-X14 is C when it forms a direct bond to RA, RB, RC, or RD; wherein RA, RB, RC, and RD each independently represent mono to the maximum allowable substitution, or no substitution; wherein each RA, RB, RC, and RD 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; wherein RD represents mono to the maximum allowable substitution at least one RD is not hydrogen; and wherein any two substituents are optionally joined or fused together to form a ring.

    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.
