First claim

The invention claimed is:

1. A compound of Formulas 3 to 11 below:

wherein
X 1 and X 2 are each independently O or S, wherein the case where both X 1 and X 2 are O is excluded,
A ring and B ring are each independently a C 6 -C 60 aryl group and may be substituted with at least one R,
L 1 and L 2 are each independently a single bond or a C 6 -C 60 arylene group,
Ar 1 is a C 6 -C 60 aryl group,
N is an integer of 0 to 4,
o and p are each an integer of 0 to 2,
R, R 1 and R 2 are each independently selected from the group consisting of deuterium; tritium; halogen; a C 6 -C 60 aryl group; a fluorenyl group; a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P; a C 1 -C 50 alkyl group; a fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; a C 2 -C 20 alkenyl group; a C 1 -C 30 alkoxy group; and a C 6 -C 30 aryloxy group, wherein two R 1 s and/or two R 2 s do not form a ring where n, o and/or p are 2, and
each of the above aryl group, fluorenyl group, heterocyclic group, fused ring group, alkyl group, alkenyl group, alkoxy group, and aryloxy group of R, R 1 and R 2 , the aryl group of Ar 1 , and the arylene group of L 1 and L 2 may be substituted with one or more substituents selected from the group consisting of deuterium; halogen; a silane group; a siloxane group; a boron group; a germanium group; a cyano group; a nitro group; a C 1 -C 20 alkylthio group; a C 1 -C 20 alkoxy group; a C 1 -C 20 alkyl group; a C 2 -C 20 alkenyl group; a C 2 -C 20 alkynyl group; a C 6 -C 20 aryl group; a C 6 -C 20 aryl group substituted with deuterium; a fluorenyl group; a C 2 -C 20 heterocyclic group; a C 3 -C 20 cycloalkyl group; a C 7 -C 20 arylalkyl group; and a C 8 -C 20 arylalkenyl group.
