The ligand 2,6-bis[(N-phenyl)amido]-4-methylphenol (receptor 1) and its copper(II) complex (receptor 2) having amide moiety have been designed and synthesized for selective sensing of anions. The anion recognition behavior of the receptor 1 and its copper complex (receptor 2) has been studied in acetonitrile. Quenching of fluorescence was observed for both receptors in presence of HSO4(-) anion whereas other physiologically and environmentally important anions such as F(-), Cl(-), Br(-), I(-), CN(-), OAc(-), HCO₃(-), H₂PO₄(-), NO₃(-), NO₂(-) and SO₄(2-) show fluorescence enhancement behavior. The sensing protocol has been studied both spectrophotometrically as well as spectrofluorometrically. Fluorescence quenching is suggested to proceed via both dynamic and static processes.
已设计并合成了具有酰胺部分的配体2,6-双[（N-苯基）氨基]-4-甲基苯酚（受体1）及其铜（II）配合物（受体2），用于选择性识别阴离子。在乙腈中研究了受体1及其铜配合物（受体2）的阴离子识别行为。在HSO4(-)阴离子存在下，两种受体均观察到荧光猝灭，而其他生理和环境中重要的阴离子，如F(-)、Cl(-)、Br(-)、I(-)、CN(-)、OAc(-)、HCO₃(-)、H₂PO₄(-)、NO₃(-)、NO₂(-)和SO₄(2-)则表现出荧光增强行为。已通过分光光度法和荧光分光光度法研究了传感方案。荧光猝灭被认为是通过动态和静态过程进行的。
