| titleOfInvention | A kind of preparation method of long-acting photochromic compound based on cyclodextrin modification and its application in contact lens |
| abstract | The present invention relates to a cyclodextrin-modified long-acting photochromic compound and its application in contact lenses. The cyclodextrin-modified compound comprises the following components: at least one photochromic group; at least one A hindered amine or hindered phenol light stabilizer group; at least one ultraviolet light absorber group; the present invention forms a photochromic small molecule, a light stabilizer and an ultraviolet light absorber by bonding the cyclodextrin molecule to form The cyclodextrin compound with long-term photosensitivity can significantly enhance the light resistance of the photochromic group under the action of the light stabilizer and the ultraviolet light absorber, and prolong the discoloration life of the photochromic contact lens. |
