1. An organic light-emitting compound represented by the following Chemical Formula A:

OG Complex Work Unit Chemistry
wherein,
R1 to R8, which may be same or different, are each independently a hydrogen atom or a deuterium atom,
Ar1 and Ar2, which may be same or different, are each independently an at least partially deuterated aryl of 6 to 50 carbon atoms or an at least partially deuterated alkyl of 1 to 30 carbon atoms,
n is an integer of 0-3 wherein when n is 2 or larger, the Ar1's may each be same or different,
m is an integer of 0-4 wherein when m is 2 or larger, the Ar2's may each be same or different,
with a proviso that n+m is not 0,
the carbon atoms of the aromatic rings in the dibenzofuran moiety may be hydrogenated or deuterated when Ar1 or Ar2 is not bonded thereto,
L1 is a linker represented by the following Structural Formula B,

OG Complex Work Unit Chemistry
wherein,
two of substituents R11 to R20 are single bonds connected respectively to the anthracenyl moiety and the dibenzofuran moiety in the compound of Chemical Formula A,
the remaining eight, other than the two single bonds, among substituents R11 to R20, may be same or different and 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 alkenyl of 2 to 30 carbon atoms, a substituted or unsubstituted alkynyl of 2 to 30 carbon atoms, a substituted or unsubstituted cycloalkyl of 3 to 30 carbon atoms, a substituted or unsubstituted cycloalkenyl of 5 to 30 carbon atoms, a substituted or unsubstituted alkoxy of 1 to 30 carbon atoms, a substituted or unsubstituted aryloxy of 6 to 30 carbon atoms, a substituted or unsubstituted alkylthioxy of 1 to 30 carbon atoms, a substituted or unsubstituted arylthioxy of 5 to 30 carbon atoms, a substituted or unsubstituted alkylamine of 1 to 30 carbon atoms, a substituted or unsubstituted arylamine of 5 to 30 carbon atoms, a substituted or unsubstituted aryl of 6 to 50 carbon atoms, a substituted or unsubstituted heteroaryl of 2 to 50 carbon atoms bearing O, N, or S as a heteroatom, a cyano, a nitro, a halogen, a substituted or unsubstituted alkylsilyl of 1 to 30 carbon atoms, and a substituted or unsubstituted arylsilyl of 6 to 30 carbon atoms,
wherein the term ‘substituted’ in the expression “a substituted or unsubstituted” 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 cycloalkyl of 3 to 24 carbon atoms, a halogenated alkyl of 1 to 24 carbon atoms, an aryl of 6 to 24 carbon atoms, an arylalkyl of 7 to 24 carbon atoms, a heteroaryl of 2 to 24 carbon atoms, an alkoxy of 1 to 24 carbon atoms, an alkylsilyl of 1 to 24 carbon atoms, an arylsilyl of 6 to 24 carbon atoms, and an aryloxy of 6 to 24 carbon atoms.
