Compound and organic light-emitting element comprising same

A compound of Chemical Formula 1:

• wherein, in Chemical Formula 1:
• R1 to R8 are the same as or different from each other, and are each independently hydrogen, deuterium, a halogen group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
• Ar1 is a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
• L is a direct bond or a substituted or unsubstituted arylene group;
• Q is any one of the groups of the following Chemical Formulae 2-1 to 2-6,
• wherein in Chemical Formulae 2-1 to 2-6:
• X and Y are the same as or different from each other, and are each independently O or S;
• any one of R9 to R16 is linked to L of Chemical Formula 1;
• the other groups which are not linked to L of Chemical Formula 1 among R9 to R16 are the same as or different from each other, and are each independently hydrogen, deuterium, a halogen, a cyano group, a silyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group,
• provided that in Chemical Formula 1, when L is a direct bond, Q is Chemical Formula 2-2, both X and Y are O, and any one of R9 to R14 and R16 is linked to L of Chemical Formula 1, if any one of Ar1 and R15 is an unsubstituted phenyl group, the other is a substituted or unsubstituted aryl group having 10 to 60 carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 60 carbon atoms.
