Spirooxazine type hydrogen ion fluorescent probe compound based on 1,8-naphthalimide unit, and synthesis method and application of compound

The invention provides a spirooxazine type hydrogen ion fluorescent probe compound based on a 1,8-naphthalimide unit, and a synthesis method and application of the compound. According to the invention, photochromic base spirooxazine is bonded to a naphthalimide unit to obtain a difunctional photochromic material; when naphthalimide is substituted, dimethylamino is introduced through a novel method; the final compound is yellow before illumination, is green after illumination and has an obvious photochromic effect; the compound emits bright green fluorescence by own, and after acid is added, color changes; and in addition, the value of the bright green fluorescence emitted by the compound is obviously lowered. The compound belongs to the spirooxazine compound which simultaneously has photochromic performance and can emit the fluorescence, and the compound also has a fluorescent probe function capable of identifying hydrogen ions. 本发明提供了基于1,8-萘酰亚胺单元的螺噁嗪类氢离子荧光探针化合物及其合成方法和应用，本发明通过在萘酰亚胺单元上键接光致变色基螺噁嗪得到一种双功能光致变色材料，其
