wherein, in Chemical Formula 1,
R 1 to R 4 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C30 aryl group,
Ar 3 to Ar 6 are each independently hydrogen, or a substituted or unsubstituted C6 to C30 aryl group,
m1 and m4 are each independently one of integers of 1 to 4,
m2 and m3 are each independently one of integers of 1 to 3,
at least one of R 1 to R 4 is deuterium,
Ar 1 and Ar 2 are each independently one selected from the substituents listed in Group I and Group II, and
at least one of Ar 1 and Ar 2 is one selected from the substituents listed in Group II;

wherein, in Group I and Group II,
R a and R b are each independently hydrogen, deuterium, a cyano group, or a substituted or unsubstituted C1 to C10 alkyl group,
R c to R e are each independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,
D is deuterium,
m5 and m8 are each independently one of integers of 1 to 5,
m6 and m9 are each independently one of integers of 1 to 4, and
m7 and m10 are each independently one of integers of 1 to 3.

2 . The compound for an organic optoelectronic device of claim 1 , wherein:

in Chemical Formula 1-1 to Chemical Formula 1-10, Ar 1 to Ar 6 , R 1 to R 4 and m 1 to m 4 are defined the same as those of Chemical Formula 1.

3 . The compound for an organic optoelectronic device of claim 1 , wherein:
Ar 1 and Ar 2 in Chemical Formula 1 are each independently one selected from the substituents listed in Group I-1 and Group II-1, and at least one of Ar 1 and Ar 2 is one selected from the substituents listed in Group II-1

in Group I-1 and Group II-1, * is a linking point.

4 . The compound for an organic optoelectronic device of claim 1 , wherein;
Chemical Formula 1 is represented by Chemical Formula 1-8a or Chemical Formula 1-8e:

in Chemical Formula 1-8a and Chemical Formula 1-8e,
Ar 1 and Ar 2 are defined the same as those of Chemical Formula 1, and
Ar 6 is a C6 to C30 aryl group that is unsubstituted or substituted with deuterium.

5 . The compound for an organic optoelectronic device of claim 1 , wherein the compound is a compound of Group 1:
