More Information
Summary:The present invention relates to an organic compound and an organic electroluminescent element comprising the same, wherein the compound is represented by a chemical formula 1 shown in the specification. As a novel organic compound, the organic compound has a high T1 value and a deep HOMO energy level, a hole and an electron form a charge balance, and luminescence is realized inside a luminescent layer instead of a hole transport layer interface, thereby significantly improving the luminous efficiency and lifetime characteristics of an organic electroluminescent element. More specifically, the present invention provides an organic electroluminescent element having significantly improved luminous efficiency and lifespan. The chemical formula 1 is shown in the specification. 本发明涉及有机化合物以及包含该化合物的有机电致发光元件，所述化合物以下述化学式1表示。本发明作为新型有机化合物，具有高T1值和深HOMO能级且空穴和电子形成电荷平衡(charge balance)，并在发光层内部实现发光，而不是空穴传输层界面，从而显著地改善有机电致发光元件的发光效率以及寿命特性。更详细地提供一种显著地改善发光效率以及寿命的有机电致发光元件。[化学式1]
