【摘要】 合成了2-氟-3-吡啶酯基硫桥杯[4]芳烃衍生物F(C₆₄H₅₆F₄N₄O₈S₄),并通过¹H NMR核磁共振,¹⁹F NMR核磁共振,IR进行了初步表征。通过荧光光谱实验研究了衍生物F对K⁺,Ca²⁺,Mg²⁺,Pb²⁺,Hg²⁺等多种不同金属离子的荧光响应。结果表明,F对Pb²⁺表现出很好的荧光猝灭效应和良好的选择专一性。更多还原

【Abstract】 2- fluoro- 3- pyridine- thiacalix[4]arene F( C₆₄H₅₆F₄N₄O₈S4) was synthesized and characterized by¹H NMR,¹⁹F NMR and IR. Fluorescence techniques was used for the analysis of F towards different kinds of ions such as K+,Ca²⁺,Mg²⁺,Pb²⁺,Hg²⁺. It figured out that F showed remarkable fluorescence quenching effect and good specificity for P²⁺.更多还原
