| 摘 要： | 合成了一种菁染料-β-环糊精化合物(Dye-β-CD),采用紫外-可见光谱法探讨了以Dye-β-CD作为带有荧光探针的主体化合物在水质分析中的应用。结果表明,Dye-β-CD能够在pH=7.2的缓冲溶液介质中对Cu2+进行定量识别,根据Benesi-Hildebrand方程确定Dye-β-CD与硫酸铜包结比为1,其包合常数为5.47×104 L/mol,表明Dye-β-CD是一种优良的带有荧光探针的主体化合物。

| Abstract: | A cyanine dye-β-cyclodextrin(Dye-β-CD) was synthesized.The Dye-β-CD as host compounds with fluorescent probes was studied in supramolecular inclusion complexes by UV-vis spectral titration.The results showed that Dye-β-CD could be determind,Dye-β-CD and bluestone could form inclusion complexes with a ratio of 1∶ 1 under pH value of 7.2.The corresponding inclusion constant was 5.47×104 L/mol according to the Benesi-Hildebrand equation.It was indicated that the Dye-β-CD was an excellent host compound with a fluorescent probe. |
