First claim

1 . A compound for an organic optoelectronic device, the compound being represented by Chemical Formula 1:

wherein, in Chemical Formula 1,
Ar 1 and Ar 2 are each independently a substituted or unsubstituted C6 to C30 aryl group,
L 1 and L 2 are each independently a single bond or a substituted or unsubstituted C6 to C30 arylene group,
R 1 to R 4 are each independently hydrogen, deuterium, or a substituted or unsubstituted C6 to C30 aryl group,
R 5 and R 6 are each independently hydrogen or deuterium,
n 1 , n 3 , and n 4 are each independently an integer of 1 to 4,
n2 and n5 are each independently integer of 1 to 3, and
n6 is an integer of 1 to 5.

2 . The compound for an organic optoelectronic device as claimed in claim 1 , wherein:
the compound is represented by Chemical Formula 1-1:

in Chemical Formula 1-1, Ar 1 , Ar 2 , R 1 to R 6 , L 1 , L 2 , and n1 to n6 are defined the same as those of Chemical Formula 1.

3 . The compound for an organic optoelectronic device as claimed in claim 1 , wherein R 1 to R 4 are each independently hydrogen, deuterium, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted phenanthrenyl group, or a substituted or unsubstituted triphenylene group.

4 . The compound for an organic optoelectronic device as claimed in claim 1 , wherein Ar 1 and Ar 2 are each independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted phenanthrenyl group, a substituted or unsubstituted triphenylene group, a substituted or unsubstituted dibenzofuranyl group, or a substituted or unsubstituted dibenzothiophenyl group.

5 . The compound for an organic optoelectronic device as claimed in claim 1 , wherein:
moieties *-L 1 -Ar 1 and *-L 2 -Ar 2 are each independently a moiety of Group I:

in Group I, * is a linking point.

6 . The compound for an organic optoelectronic device as claimed in claim 1 , wherein the compound is a compound of Group 1:

7 . An organic photoelectronic device, comprising:
an anode and a cathode facing each other, and at least one organic layer between the anode and the cathode, wherein the at least one organic layer includes the compound for an organic optoelectronic device as claimed in claim 1 .

8 . The organic photoelectronic device as claimed in claim 7 , wherein:
the at least one organic layer includes a light emitting layer, and the light emitting layer includes the compound.

9 . A display device comprising the organic photoelectronic device as claimed in claim 7 .
