Abstract: The present disclosure relates to an organic compound including an electron acceptor moiety of a hetero aromatic ring having at least one nitrogen as a nuclear atom and an electron donor moiety of a fused aromatic or a fused hetero aromatic ring linked to the electron acceptor moiety directly or via a linker moiety, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound includes both the electron acceptor and donor moieties, thus charges can be transported easily within the molecule. The OLED and the organic light emitting device including the organic compound, which may comprise at least one substituent having strong electron withdrawing property at specific position, in an emissive layer can implement excellent luminous efficiency and luminous lifespan.
