  • Publication number: 20240090326
    Abstract: The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound can be a bipolar compound having a p-type moiety and an n-type moiety and has high energy level and proper energy bandgap for an emissive layer of the OLED. As the organic compound is applied into the emissive layer, the OLED can maximize its luminous properties as holes and electrons are recombined uniformly over the whole area in an emitting material layer (EML).

  • Patent number: 11492330
    Abstract: An organic compound having a naphtho fluoranthene core and a hetero aromatic group bonded to a specific position of the naphtho fluoranthene core, an organic light-emitting diode and an organic light-emitting device including the compound are disclosed. Since the organic compound has a narrow Stokes Shift between an absorption wavelength and an emission wavelength, the organic compound has a broad overlapped area between its absorption peak and an emission peak of a delayed fluorescent material, and therefore it can emit blue light with high color purity. It is possible to manufacture an organic light-emitting diode (OLED) and an organic light-emitting device that enhance luminous efficiency and color purity using the organic compound.
