Zusammenfassung: | The invention discloses a metal-organic framework loaded spiropyrane photochromic dual material and a preparation method thereof, and belongs to the field of organic solid photochromic materials. Spiropyrane is loaded into the light-emitting metal organic framework CQDs (at) ZIF-8 coated with the carbon quantum dots, and the metal-organic framework provides enough space free volume for spiropyrane molecules, so that spiropyrane has enough open-loop space in a solid state, and the color change performance of spiropyrane is improved. And the large coincidence range of the fluorescence emission wavelength of the carbon quantum dots and the ultraviolet absorption wavelength of the spiropyrane is utilized, so that energy transfer can occur between the carbon quantum dots and the spiropyrane, the dynamic change of the fluorescence color of the material is realized, and the material has a wide application prospect in the anti-counterfeiting field.
