Claim 11:
12. A consumer product comprising an organic light-emitting device (OLED) that includes an anode, a cathode; and an organic layer disposed between the anode and the cathode, the organic layer comprising a compound of Formula I, wherein
Y is selected from the group consisting of NAr, O, S, and Se;
Ar is an optionally substituted aryl or optionally substituted heteroaryl;
Z1 to Z 8 are independently selected from C or N, wherein at least one of Z2 or Z3 is c, and at least one of Z6 or Z7 is C;
RA and RB represent mono to the maximum allowable substitution, or no substitution;
each RA and RB is independently hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, cyclic amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; or optionally, any two adjacent substituents join to form a ring; with the proviso that RB does not comprise an amino group;
R is selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof or a triphenylsilyl group and a ring group that connects to the silicon, the ring group selected from the group consisting of quinazoline, carbazole, dibenzothiophene, dibenzofuran, benzo[d]benzo[4,5]imidazo[2,1-b]oxazole, benzo[d]benzo[4,5]imidazo[2,1-b]thiazole, and benzo[d]benzo[4,5]imidazo[3,2-a]imidazole; or optionally R can join with Ar to form a ring; and
with the provisos that R is not N-methyl-benzimidazole, and the compound is not compound A, , and
with the proviso that the compound of Formula I satisfies at least one of conditions (i) and (ii):
(i) two adjacent groups RA or two adjacent groups Rb join to form a fused carbazole ring; and
(ii) Y is Se.
