OG Complex Work Unit Chemistry
wherein, in Chemical Formula 1:
X1 to X3 are each independently N or CH, provided that at least two of X1 to X3 are N;
Y1 and Y2 are each independently O or S;
L is a single bond, a substituted or unsubstituted C6-60 arylene, or a substituted or unsubstituted C2-60 heteroarylene containing one or more heteroatoms selected from the group consisting of N, O, and S, provided that L is bonded to a position *2;
Ar1 and Ar2 are each independently a substituted or unsubstituted C6-60 aryl, or a substituted or unsubstituted C2-60 heteroaryl containing one or more heteroatoms selected from the group consisting of N, O, and S; and
R1 to R4 are each independently hydrogen, deuterium, a halogen, cyano, nitro, amino, silyl, a substituted or unsubstituted C1-60 alkyl, a substituted or unsubstituted C1-60 haloalkyl, a substituted or unsubstituted C1-60 alkoxy, a substituted or unsubstituted C1-60 haloalkoxy, a substituted or unsubstituted C3-60 cycloalkyl, a substituted or unsubstituted C2-60 alkenyl, a substituted or unsubstituted C6-60 aryl, a substituted or unsubstituted C6-60 aryloxy, or a substituted or unsubstituted C2-60 heteroaryl containing one or more heteroatoms selected from the group consisting of N, O, and S, or adjacent substituents are combined with each other to form a C6-60 aromatic ring, a C6-60 non-aromatic ring, or a C2-60 heteroaromatic ring containing one or more heteroatoms selected from the group consisting of N, O, and S.
