Ar 1 and Ar a are each independently a substituted or unsubstituted C6 to C30 aryl group, and
R 1a to R 8a , R 1b to R 8b and R 1c to R 8c are each hydrogen.

3. The organic compound of claim 1 , wherein Ar 1 to Ar 3 are each independently groups listed in the following Group 1 or the group represented by Chemical Formula A, and
one or two of Ar 1 to Ar 3 is the group represented by Chemical Formula A

wherein, in Group 1,
R 9 to R 70 are independently hydrogen or a C6 to C30 aryl group, and
* indicates a linking point.

4. An organic compound, wherein the organic compound is one of the compounds listed in the following Group 2:

5. An organic optoelectric diode, comprising:
an anode and a cathode facing each other, and
at least one organic layer positioned between the anode and the cathode,
wherein the organic layer comprises the compound of claim 1 .
