| titleOfInvention | A kind of photochromic compound and the preparation method and application thereof |
| abstract | The invention discloses a kind of photochromic compound, structure as shown in formula A, Wherein, R is fluorophor, is substituted or unsubstituted naphthalene, anthracene, xanthene, pyrene, 1,8- naphthalimide, cumarin or pyrans nitrile, and the substituent group on R is C 1~4 Alkyl, halogen, hydroxyl, C 1~4 Alkoxy or C 1~4 Alkylamino radical；X is oxygen, and Y is C (CH 3 ) 2 ；Or X is N (CH 3 ), Y is C (O)；The invention also discloses the isomers of the photochromic compound, and its mixture with isomers, also disclose the preparation method and application of the photochromic compound.The maximum absorption wavelength of the photochromic groups of the photochromic compound is in visible region, and the maximum absorption wavelength of fluorophor effectively prevents the overlapping of two kinds of group maximum absorption wavelengths in ultra-violet (UV) band and near visible area.The photochromic compound has significant special absorption and emission characteristics in Uv and visible light area, can make photochromic fluorescent switch and Molecular Logic Gates. |
