| titleOfInvention | Preparation method and application of fluorescent photochromic material with crystalline light response |
| abstract | A preparation method and application of fluorescent photochromic material with crystalline light response belong to the field of organic intelligent materials. In the invention, a novel double rhodamine molecule with crystalline photochromic behavior is discovered. The double rhodamine molecule has cis-trans isomerism, and single crystals of two isomers can change blue fluorescence into orange-red fluorescence under the irradiation of ultraviolet light of 375 nm. The material is used for carrying out photoetching experiments, different templates are selected, and various patterns can be obtained under the irradiation of a portable ultraviolet lamp. Substances with crystalline state photoluminescence discoloration behaviors discovered by the invention are very rare, and only few substances have the crystalline state photoluminescence discoloration behaviors at present. The synthetic route provided by the invention is simple and efficient, the operation is simple and the time consumption is short through one-step reaction, and the yield can reach more than 70%. |
