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.

Abstract: An organic compound having a spiro-anthracene core and an aromatic or heteroaromatic group and/or an amino group bonded to the core, and an organic light-emitting diode and an organic light-emitting device including the organic compound are disclosed. Since the organic compound of the present disclosure has a rigid structure and a substantially narrow full width at half maximum (FWHM), it is possible to manufacture an organic light-emitting diode and an organic light-emitting device with lowered driving voltages and enhanced luminous efficiency and color purity using the organic compound.

Abstract: An organic light emitting diode comprises an emitting material layer implementing a delayed fluorescence and another emitting material layer disposed adjacently to the emitting material layer and implementing fluorescence or phosphorescence and an organic light emitting device including the diode. As exciton generated in the plural emitting material layer drops to a ground state through the luminous materials each of which has a controlled energy level, it is possible to implement excellent luminous efficiency derived from a delayed fluorescent material and improved color purity derived from a fluorescent or phosphorescent material having narrow FWHM.
