The invention discloses a method for synthesizing an ultrashort-wavelength photochromic diarylethene compound by using imidazole-thiophene aromatic heterocycle and an application of the compound. A photochromic material can maintain good photochromic performance in a solution or film, has weaker fluorescence when the open-loop state ranges from 265 nm to 276 nm, has high fluorescence when the closed-loop state ranges from 400 nm to 550 nm, can be applied to a fluorescent photoswitch, an anti-forgery technology, a short-wavelength high-density holographic optical storage material and the like, and compared with the symmetrical thiophene or benzothiophene octafluorocyclopentene material, the material preparing cost is lower, and the application prospect is broader.
