  • Publication number: 20220077401
    Abstract: The present disclosure relates to an organic compound in which an electron acceptor moiety and an electron donor moiety of a fused aromatic ring or a hetero aromatic ring are directly linked or through an linker moiety and they are connected via carbon-carbon bond, 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 that are linked directly or through a linker moiety via a carbon-carbon bond having strong bond energy within its molecule, thus charges can be transported easily within the molecule. The OLED and the organic light emitting device including the organic compound in an emissive layer can implement excellent luminous efficiency and luminous lifespan.
