Z 1 to Z 13 are independently N or CR a , provided that at least one of Z 1 to Z 13 is N,
R a is independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a C6 to C18 aryl group, or a combination thereof, and
the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C4 alkyl group, or a C6 to C18 aryl group,

wherein, in Group I,
is a linking point.

2. The compound of claim 1 , which is represented by Chemical Formula at least one of 1-A, 1-B, 1-C, 1-D, 1-E, 1-F, 1-G, 1-H, 1-I, or 1-J:

wherein, in Chemical Formulae 1-A to 1-J,
Ar 1 to Ar 4 are independently selected from substituents of Group I, and
R a1 to R a10 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a C6 to C18 aryl group, or a combination thereof,

wherein, in Group I,
is a linking point.
