The present disclosure relates to an organic compound including an electron acceptor moiety of a hetero aromatic ring having at least one nitrogen as a nuclear atom and an electron donor moiety of a fused aromatic or a fused hetero aromatic ring linked to the electron acceptor moiety directly or via a linker moiety, 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, thus charges can be transported easily within the molecule. The OLED and the organic light emitting device including the organic compound, which may comprise at least one substituent having strong electron withdrawing property at specific position, in an emissive layer can implement excellent luminous efficiency and luminous lifespan.
本公开涉及一种有机化合物,包括具有至少一个氮原子作为核原子的杂环芳香环的电子受体基团和与电子受体基团直接或通过连接基团连接的融合芳香或融合杂环芳香环的电子给体基团,以及包括该有机化合物的有机发光二极管(OLED)和有机发光器件。该有机化合物包括电子受体和给体基团,因此电荷可以在分子内轻松传输。包括该有机化合物的OLED和有机发光器件,可能在发射层中包含至少一个在特定位置具有强电子吸引性的取代基,可以实现出色的发光效率和发光寿命。
