1. A compound represented by the following Chemical Formula 1:

OG Complex Work Unit Chemistry
wherein in Chemical Formula 1,
X1 is O or S,
A1 is a substituted or unsubstituted aromatic hydrocarbon ring; a substituted or unsubstituted aliphatic hydrocarbon ring; or a substituted or unsubstituted fused ring of aromatic hydrocarbon ring and aliphatic hydrocarbon ring,
at least one of Y1 and Y2 is deuterium; a cyano group; a halogen group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, or bonds to adjacent groups to form an aromatic hydrocarbon ring; a fused ring of aromatic hydrocarbon ring and aliphatic hydrocarbon ring; or a heteroring, and the remainder is hydrogen,
with the proviso that when the at least one of Y1 and Y2 is a phenyl group, the at least one of Y1 and Y2 is a phenyl group substituted with one or more selected from the group consisting of deuterium; F; a cyano group; a trideuteriummethyl group; a cumyl group; a cumyl group substituted with deuterium; a trifluoromethyl group (CF3); a trimethylsilyl group; and combinations thereof,
Z1 is hydrogen; deuterium; a halogen group; a cyano group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted arylalkyl group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted silyl group; a substituted or unsubstituted amine group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fused ring group of aromatic hydrocarbon ring and aliphatic hydrocarbon ring; or a substituted or unsubstituted heterocyclic group,
R1 to R3 and R11 are the same as or different from each other, and each independently hydrogen; deuterium; a halogen group; a cyano group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted arylalkyl group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted silyl group; a substituted or unsubstituted amine group; a substituted or unsubstituted aryl group; a substituted or unsubstituted fused ring group of aromatic hydrocarbon ring and aliphatic hydrocarbon ring; or a substituted or unsubstituted heterocyclic group, or adjacent groups among R1 to R3 and R11 bond to each other to form a substituted or unsubstituted hydrocarbon ring,
r1 is 1 or 2,
when r1 is 2, the two R1s in the parentheses are the same as or different from each other,
r2, r3 and r11 are each an integer of 1 to 4,
when r2 is 2 or greater, the two or more R2s in the parentheses are the same as or different from each other,
when r3 is 2 or greater, the two or more R3s in the parentheses are the same as or different from each other,
when r11 is 2 or greater, the two or more R11s in the parentheses are the same as or different from each other, and
