Organic compounds and organic light-emitting device comprising the same

An organic compound represented by Formula 1:

• wherein the moieties X are the same as or different from each other and are each independently N or CR, the groups R are the same as or different from each other and are each independently selected from hydrogen, deuterium, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C6-C50 aryl, substituted or unsubstituted C2-C50 heteroaryl, and cyclic groups in which a substituted or unsubstituted C3-C30 aliphatic ring and a C5-C30 aromatic ring are fused together, A1 and A2 are the same as or different from each other and are each independently selected from substituted or unsubstituted C6-C50 aryl, substituted or unsubstituted C2-C50 heteroaryl, and cyclic groups in which a substituted or unsubstituted C3-C30 aliphatic ring and a C5-C30 aromatic ring are fused together, R1 to R3 are the same as or different from each other and are each independently selected from hydrogen, deuterium, substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C2-C30 alkynyl, substituted or unsubstituted C2-C30 alkenyl, substituted or unsubstituted C6-C50 aryl, substituted or unsubstituted C3-C50 cycloalkyl, substituted or unsubstituted C2-C50 heterocycloalkyl, substituted or unsubstituted C2-C50 heteroaryl, and cyclic groups in which a substituted or unsubstituted C3-C30 aliphatic ring and a C5-C30 aromatic ring are fused together, L1 to L6 are the same as or different from each other and each independently represent a single bond or are each independently selected from substituted or unsubstituted C6-C30 arylene, substituted or unsubstituted C2-C30 heteroarylene, and divalent cyclic groups in which a substituted or unsubstituted C3-C24 aliphatic ring and a C5-C24 aromatic ring are fused together, a1 to a3 are integers from 1 to 3, provided that when a1 to a3 are integers greater than or equal to 2, the groups R1 to R3 are the same as or different from each other, respectively, each of n, o, p, s, t, and u is an integer of 1 or 2, provided that when n, o, p, s, t, and u are integers greater than or equal to 2, L1 to L6 are the same as or different from each other, respectively, m is an integer from 1 to 4, provided that when m is an integer greater than or equal to 2, the bracketed structures are the same as or different from each other, with the proviso that adjacent ones of the groups R are optionally linked to each other to form an alicyclic or aromatic monocyclic or polycyclic ring, the “substituted” in the definitions of X, A1, A2, R1 to R3, and L1 to L6 in Formula 1 indicating substitution with one or more substituents selected from deuterium, C1-C24 alkyl, C1-C24 haloalkyl, C2-C24 alkenyl, C2-C24 alkynyl, C3-C30 cycloalkyl, C1-C24 heteroalkyl, C6-C30 aryl, C7-C30 arylalkyl, C7-C30 alkylaryl, C2-C30 heteroaryl, C2-C30 heteroarylalkyl, C3-C30 alkylheteroaryl, cyclic groups in which a substituted or unsubstituted C3-C24 aliphatic ring and a C5-C24 aromatic ring are fused together, C1-C24 alkoxy, C1-C30 amine, C1-C30 silyl, C1-C30 germanium, C6-C24 aryloxy, C6-C24 arylthionyl, cyano, halogen, hydroxyl, and nitro, or a combination thereof, provided that when substituted with two or more substituents, the substituents are identical to or different from each other, the “unsubstituted” in the same definition indicating having no substituent, and one or more hydrogen atoms in each of the substituents being optionally replaced by deuterium atoms.
