The invention belongs to the technical field of organic photoelectric materials, and discloses an organic micromolecule material based on a 2,6-dimethyl-4-cyanophenyl receptor unit, preparation and application. The organic micromolecule material has a structural formula as shown in formula (I), and Ar in the formula shows a phenyl aromatic amine heterocycle or phenyl aromatic amine donor unit. Thematerial has a weak intramolecular charge transfer state, and thus, fluorescence emission of a zone from dark blue to ultraviolet can be realized. Meanwhile, because the molecules have quite short effective conjugated length, the material has high triplet state energy level. In the application of an organic electroluminescent device, the problem of unbalanced charge carriers of a unipolar organicphotoelectric material can be solved effectively, therefore, the structure of the device is simplified, and the performance of the device is improved.
