Anthracene compound and organic light-emitting device comprising same

An anthracene compound represented by the following Chemical Formula A:

• wherein,
• Ar1 is a substituted or unsubstituted aryl of 6 to 18 carbon atoms or a substituted or unsubstituted heteroaryl of 2 to 18 carbon atoms,
• R1 to R8 and R11 to R14, which are same or different, are each independently selected from a hydrogen atom, a deuterium atom, a substituted or unsubstituted alkyl of 1 to 30 carbon atoms, a substituted or unsubstituted aryl of 6 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl of 3 to 30 carbon atoms, a substituted or unsubstituted heteroaryl of 2 to 50 carbon atoms, a substituted or unsubstituted alkylsilyl of 1 to 30 carbon atoms, a substituted or unsubstituted arylsilyl of 6 to 30 carbon atoms, a cyano, and a halogen, one of R11 to R14 being a single bond to L1,
• R9 is any one selected from a substituted or unsubstituted alkyl of 1 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl of 3 to 30 carbon atoms, a substituted or unsubstituted aryl of 6 to 18 carbon atoms, and a substituted or unsubstituted heteroaryl of 2 to 18 carbon atoms,
• R10 is a hydrogen atom or a deuterium atom,
• X is an oxygen atom (O) or a sulfur atom (S),
• L1, which functions as a linker, is a single bond or any one selected from a substituted or unsubstituted arylene of 6 to 20 carbon atoms, and a substituted or unsubstituted heteroarylene of 2 to 20 carbon atoms, and
• n is an integer of 1 to 3 wherein when n is 2 or more, the corresponding L1's are same or different,
• the anthracene compound represented by Chemical Formula A includes at least one deuterium atom,
• wherein the term “substituted” in the expression “substituted or unsubstituted” used for compounds of Chemical Formula A means having at least one substituent selected from the group consisting of a deuterium atom, a cyano, a halogen, a nitro, an alkyl of 1 to 24 carbon atoms, a halogenated alkyl of 1 to 24 carbon atoms, cycloalkyl of 3 to 30 carbon atoms, an aryl of 6 to 24 carbon atoms, an arylalkyl of 7 to 24 carbon atoms, an alkylaryl of 7 to 24 carbon atoms, a heteroaryl of 2 to 24 carbon atoms, an alkylsilyl of 1 to 24 carbon atoms, and an arylsilyl of 6 to 24 carbon atoms.
