Abstract: The present disclosure relates to an organic compound having the following structure of Chemical Formula 1, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound includes a triazine moiety of an electron acceptor and a fused hetero aromatic moiety of an electron donor separated from the triazine moiety. The organic compound includes the electron acceptor moiety and the electron donor moiety in a single molecule, thus charges can be moved in the molecule. Also, since the organic compound includes the rigid fused hetero aromatic ring, three dimensional conformation of the organic compound is limited, and therefore the compound may have excellent luminous efficiency and color purity.
