The invention discloses an organic compound with a structure represented by a formula (I), wherein the LUMO energy level of the compound is reduced by linking an aza aromatic ring structure (a structure represented by a formula (II)), so that the electronic conductivity of the material is improved, and the compound is suitable for being used as an electronic material (such as an electron transportmaterial, an electron injection material, a hole blocking material and the like). According to the invention, the organic compound as an electron type material, particularly an electron transmissionmaterial, can be matched with hole type materials (such as a hole transmission material, a hole injection material and an electron blocking material), so that the transmission of electrons and holes is balanced, and the service life of a device is prolonged.
