1. An organic electroluminescent compound represented by the following formula 1:

OG Complex Work Unit Chemistry
wherein
X, Y, and Z each independently represent a single bond, O, S, NR1, or CR2R3, with a proviso that not all of X, Y, and Z are a single bond;
R1 represents a substituted or unsubstituted (C6-C30)aryl, or a substituted or unsubstituted (3- to 30-membered)heteroaryl;
R2 and R3 each independently represent a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, or a substituted or unsubstituted (3- to 30-membered)heteroaryl; or R2 and R3 may be linked to each other to form a ring(s), where if a plurality of R2 to R3 is present, each of R2, and each of R3 may be the same or different;
A1 to A4, A5 to A8, A9 to A11 and A12 to A14 each independently represent CR4 or N; and
R4 each independently represents hydrogen, deuterium, a halogen, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted mono- or di-(C6-C30)arylamino, or a substituted or unsubstituted (C1-C30)alkyl(C6-C30)arylamino; or two or more adjacent R4's may be linked to each other to form a ring(s)
wherein in R1 to R4, the substituents of the substituted alkyl, the substituted aryl, the substituted heteroaryl, the substituted cycloalkyl, the substituted mono- or di-arylamino, and the substituted alkylarylamino each independently are at least one selected from the group consisting of deuterium; a halogen; a cyano; a nitro; a (C1-C30)alkyl; a (C3-C30)cycloalkyl; a (3- to 7-membered)heterocycloalkyl; a (3- to 30-membered)heteroaryl unsubstituted or substituted with a (C6-C30)aryl(s); a (C6-C30)aryl unsubstituted or substituted with one or more of a (C1-C30)alkyl(s) and a (3- to 30-membered)heteroaryl(s); a (C6-C30)aryl(C1-C30)alkyl; and a (C1-C30)alkyl(C6-C30)aryl.
