L 1 and L 2 are independently a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C30 heteroarylene group,
A 1 and A 2 are independently hydrogen, deuterium, a substituted or unsubstituted C6 to C18 aryl group, or a substituted or unsubstituted C2 to C30 heterocyclic group, and
at least one of A 1 and A 2 comprises a moiety represented by Chemical Formula A,

wherein, in Chemical Formula A,
Z 1 to Z 5 are independently N or CR a ,
at least one of Z 1 to Z 5 is N,
R a is independently hydrogen, deuterium, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C6 to C18 aryl group,
R a is independently present or adjacent groups thereof are linked with each other to form a substituted or unsubstituted aliphatic, aromatic or heteroaromatic monocyclic or polycyclic ring, and
* is a linking point with L 1 or L 2 of Chemical Formula 1,
wherein “substituted” refers to replacement of at least one hydrogen by deuterium, a cyano group, a C1 to C20 alkyl group, a C6 to C30 aryl group, or a C2 to C30 heteroaryl group.

2. The compound for an organic optoelectronic device of claim 1 , wherein Chemical Formula A is represented by one of Chemical Formula A1, Chemical Formula A2, Chemical Formula A3, and Chemical Formula A4:

at least one of Z 1 , Z 3 , Z 5 , and Z 6 to Z 15 of Chemical Formula A1 is N,
at least one of Z 1 and Z 5 of Chemical Formulae A2 to A4 is N,
m and n are independently one of integers of 0 to 2,
R a to R e are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C6 to C18 aryl group, and
* is a linking point with L 1 or L 2 of Chemical Formula 1.

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