4,5-二(2’-氰乙基硫基)-1,3-二硫杂环戊烯-2-硫酮在甲醇钠的作用下消除一个氰乙基,形成1,3-二硫杂环戊烯-2-硫酮单钠盐,再与9,10-二(氯甲基)蒽反应生成由两个1,3-二硫杂环戊烯-2-硫酮(DMIT)单元和一个蒽单元构建的新型三组分荧光传感器.这种新的荧光分子传感器与乙酸汞(II)的反应,却生成具有强荧光的二乙酸蒽-9,10-二甲酯(4)和双(1,3-二硫杂环戊烯-2-酮-4,5-二硫)Hg(II)配合物(5),利用化合物4的强荧光性质可以选择性识别Hg(II).还在离子液中研究此荧光分子传感器特殊的荧光行为,实验结果表明随着离子液量的增加,溶液的荧光显著增强.
4,5-bis (2’-cyanoethylthio) -1,3-dithiole-2-thione eliminates a cyanoethyl group by the action of sodium methoxide to form 1,3-dithio Heterocyclopentadiene-2-thione monosodium salt, which is then reacted with 9,10-bis (chloromethyl) anthracene to give a mixture of two 1,3-dithiole-2-thione (DMIT) units And a new three-component fluorescence sensor constructed by anthracene units.The reaction of this new fluorescent molecule sensor with mercury acetate (II) led to the production of anthracene diacetate-9,10-dimethyl ester (4) with strong fluorescence and The Hg (II) complex (5) can be selectively recognized by the strong fluorescent property of compound 4 for bis (1,3-dithiolan-2-one-4,5-dithio) Hg (II) The special fluorescence behavior of this fluorescent molecule sensor was also studied in ionic liquids. The experimental results show that the fluorescence of the solution increases significantly with the increase of the amount of ionic liquid.
