First claim
Opening claim text (preview).
The invention claimed is: 1. An organic compound represented by Chemical Formula 1A or Chemical Formula 1B: wherein, in Chemical Formulae 1A and 1B, Z 1 to Z 3 are independently N or CH, at least two of Z 1 to Z 3 are N, A 1 and Ar 2 are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, or a substituted or unsubstituted pyridinyl group, L is a single bond or a substituted or unsubstituted phenylene group, X 1 and X 2 are independently O or S, R 1 to R 8 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted phenyl group, or a cyano group, and ‘substituted’ refers to replacement of at least one hydrogen of a substituent by deuterium, a C1 to C5 alkyl group, a C6 to C18 aryl group, a pyridinyl group, or a cyano group. 2. The organic compound of claim 1 , wherein: the organic compound is represented by Chemical Formula 1A, the organic compound represented by Chemical Formula 1A is represented by one of Chemical Formulae 1Aa to 1Ad: wherein, in Chemical Formulae 1Aa to 1Ad, Z 1 to Z 3 are independently N or CH, at least two of Z 1 to Z 3 are N, Ar 1 and Ar 2 are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, or a substituted or unsubstituted pyridinyl group, L is a single bond or a substituted or unsubstituted phenylene group, X 1 and X 2 are independently O or S, R 1 to R 8 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted phenyl group, or a cyano group, and ‘substituted’ refers to replacement of at least one hydrogen of a substituent by deuterium, a C1 to C5 alkyl group, a C6 to C18 aryl group, a pyridinyl group, or a cyano group. 3. The organic compound of claim 1 , wherein: the organic compound is represented by Chemical Formula 1B, the organic compound represented by Chemical Formula 1B is represented by one of Chemical Formulae 1Ba to 1Bd: wherein, in Chemical Formulae 1Ba to 1Bd, Z 1 to Z 3 are independently N or CH, at least two of Z 1 to Z 3 are N, Ar 1 and Ar 2 are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, or a substituted or unsubstituted pyridinyl group, L is a single bond or a substituted or unsubstituted phenylene group, X 1 and X 2 are independently O or S, R 1 to R 8 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted phenyl group, or a cyano group, and ‘substituted’ refers to replacement of at least one hydrogen of a substituent by deuterium, a C1 to C5 alkyl group, a C6 to C18 aryl group, a pyridinyl group, or a cyano group. 4. The organic compound of claim 1 , wherein L is a single bond, a phenylene group, or a cyano-substituted phenylene group. 5. The organic compound of claim 1 , wherein X 1 and X 2 are each O. 6. The organic compound of claim 1 , wherein the organic compound is one of compounds listed in Group 1:
