| 摘 要： | 合成了一种长链烷氧基苯腙衍生物受体R，其结构经1H NMR、13C NMR、IR和HR-MS表征。结果表明：通过紫外及裸眼实验分析，受体R在纯DMSO溶液中能够选择性识别F-、Ac-和H2PO4-离子，在5%H2O 95%DMSO体系下可高选择性单一识别F-离子。根据Benesi-Hidebrand方程及Job曲线分析可知，受体R与阴离子形成的络合常数均在3.07 ? 103 L/mol之上，且与F-形成1 : 1型氢键络合物。最后通过1H NMR滴定实验及理论计算阐述了阴离子识别过程机理的可行性。

| Abstract: | A long-chain alkoxyphenylhydrazone derivatives R has been synthesized and characterized through 1H NMR, 13C NMR, FT-IR and HR-MS. In UV-Vis and naked eye recognition experiments, the receptor R exhibited obvious spectral and color changes in response to F-, Ac- and H2PO4- in DMSO solution. Moreover, receptor R showed selectively single recognize F- in 5%H2O 95%DMSO solution.
According to the Benesi-Hidebrand equation and Job curve, the complex constants of the receptor R with anions were above 3.07 ? 103 L/mol, and form a 1 : 1 hydrogen bond complex with F-. Finally, the mechanism of anion recognition process was explained through 1H NMR titration and theoretical calculation. |
