【 英文摘要 】The present invention belongs to the field of photochromic material, The present invention discloses a compound using photochromic material spiropyran as precursor and its preparation method. Initially through hydrothermal synthesis, using N-hydroxyethyl-3, 3-dimethyl-6-nitroindoline spiropyran as the ligand, the metal-organic framework complex C16H12CuN4O6 was synthesized. Through characterization, it was found that the spiropyran ligand the ligand reacts in situ with ethylenediamine to form a Schiff base ligand, and the metal Cu is coordinated with the Schiff base ligand to form a four-coordinated complex C16H12CuN4O6. The present invention also discloses the application of the compound with photochromic spiropyran as precursor in photocatalytic degradation of dye.
