Abstract: Disclosed is an organic compound that includes a fused hetero aromatic moiety of a spiro structure as an electron donor and a triazine moiety as an electron acceptor that is linked to the electron donor via an arylene linker substituted with at least one electron withdrawing group, an organic light emitting diode and an organic light emitting device each of which applies the organic compound into at least one emitting unit. The organic compound enables the organic light emitting diode to increase its luminous efficiency and to improve its color purity.
