wherein, in Chemical Formula 1A and Chemical Formula 1B,
Z 1 to Z 3 are independently N or CR a , at least two of Z 1 to Z 3 being N,
R a and R 1 to R 10 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group, and
R b and R c are independently a substituted or unsubstituted C6 to C20 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group.

2. The compound as claimed in claim 1 , wherein:
Chemical Formula 1A is represented by Chemical Formula 1A-1 and Chemical Formula 1B is represented by Chemical Formula 1B-1:

in Chemical Formula 1A-1 and Chemical Formula 1B-1, R 1 to R 10 , R b , and R c are defined the same as those of Chemical Formulae 1A and 1B.

3. The compound as claimed in claim 1 , wherein:
the compound is represented by Chemical Formula 1A,
Chemical Formula 1A is represented by Chemical Formula 1A-1-a:

in Chemical Formula 1A-1-a, R 1 to R 10 , R b , and R c are defined the same as those of Chemical Formula 1A.

4. The compound as claimed in claim 1 , wherein R b and R c are 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 fluorenyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted carbazolyl group, or a combination thereof.

5. The compound as claimed in claim 1 , wherein:
R b and R c are independently a group of Group I:

in Group I, * is a linking point.

6. The compound as claimed in claim 1 , wherein the compound is a compound of Group 1:

7. A composition for an organic optoelectronic device, the composition comprising:
a first compound and a second compound,
wherein:
the first compound includes the compound for an organic optoelectronic device as claimed in claim 1 ,
the second compound is represented by Chemical Formula 2:

in Chemical Formula 2,
Y 1 and Y 2 are independently a single bond or a substituted or unsubstituted C6 to C20 arylene group,
Ar 1 and Ar 2 are independently a substituted or unsubstituted C6 to C20 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group, and
R 11 to R 16 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C20 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, a cyano group, or a combination thereof.

8. The composition as claimed in claim 7 , wherein:
moieties *—Y 1 —Ar 1 and *—Y 2 —Ar 2 of Chemical Formula 2 are each independently a moiety of Group II:

in Group II, * is a linking point.

9. An organic optoelectronic 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 .

10. The organic optoelectronic device as claimed in claim 9 , wherein:
the at least one organic layer includes a light emitting layer, and
the light emitting layer includes the compound for an organic optoelectronic device.

11. A display device comprising the organic optoelectronic device as claimed in claim 9 .

12. An organic optoelectronic 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 composition for an organic optoelectronic device as claimed in claim 7 .

13. The organic optoelectronic device as claimed in claim 12 , wherein
the at least one organic layer includes a light emitting layer, and
the light emitting layer includes the composition for an organic optoelectronic device.

14. A display device comprising the organic optoelectronic device as claimed in claim 12 .
