The invention belongs to the field of photoelectric materials, and specifically relates to an organic electroluminescent material. A structural formula is shown in the description. In the formula, R represents alkyl of C1-C20. The organic electroluminescent material has a relatively high LUMO energy level and relatively low HOMO energy level, and is beneficial to blue shift of luminescent wavelengths of the material. The organic electroluminescent material also has relatively high phosphorescence quantum efficiency, relatively good solubility and processability. The invention also provides a preparation method of the organic electroluminescent material, and an application of the organic electroluminescent material in an organic electroluminescent device.
