1. An organic compound having the following structure of Chemical Formula 1:

OG Complex Work Unit Chemistry
wherein each of R1 to R12 is independently selected from the group consisting of hydrogen, halogen, a cyano group, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C1-C20 alkoxy group, an unsubstituted or substituted C1-C20 alkyl amino group, an unsubstituted or substituted C6-C30 aromatic group and an unsubstituted or substituted C3-C30 hetero aromatic group, or two adjacent groups among R1 to R12 form an unsubstituted or substituted C6-C20 aromatic ring or an unsubstituted or substituted C3-C30 hetero aromatic ring, wherein at least one of R1 to R4 is a cyano group; each of R13 to R15 is independently selected from the group consisting of hydrogen, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C1-C20 alkoxy group, an unsubstituted or substituted C1-C20 alkyl amino group, an unsubstituted or substituted C6-C30 aromatic group and an unsubstituted or substituted C3-C30 hetero aromatic group; and A is a fused hetero aromatic ring having the following structure of Chemical Formula 2:

OG Complex Work Unit Chemistry
wherein each of R21 to R24 is independently selected from the group consisting of hydrogen, halogen, a cyano group, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C1-C20 alkoxy group, an unsubstituted or substituted C1-C20 alkyl amino group, an unsubstituted or substituted C6-C30 aromatic group and an unsubstituted or substituted C3-C30 hetero aromatic group, or two adjacent groups among R21 to R24 form an unsubstituted or substituted C6-C20 aromatic ring or an unsubstituted or substituted C3-C30 hetero aryl ring; and X is NR25, oxygen (O) or sulfur (S), wherein R25 is selected from the group consisting of hydrogen, an unsubstituted or substituted C1-C20 alkyl group, an unsubstituted or substituted C1-C20 alkoxy group, an unsubstituted or substituted C1-C20 alkyl amino group, an unsubstituted or substituted C6-C30 aromatic group and an unsubstituted or substituted C3-C30 hetero aromatic group.
