receptors to form stable complexes with Hg2+. As an application of this neutral Hg2+ complex, an anion-selectiveelectrode combined with a cationic additive is prepared, and exhibits an anti-Hofmeister selectivity pattern with enhanced selectivity for the iodide anion. The overall selectivity pattern of the electrode is I− > ClO4− > SCN− ≈ Br− > salicylate− > NO2− > Cl− > NO3− ≫ HCO3− > SO42− > F− > H2PO4−
合成了具有两个N-苄氧基酰胺基团的新型Hg 2+受体,它们对金属的络合能力阳离子被检查。形成的复合物的结构通过电喷雾质谱 和 1 H NMR光谱。酰胺基团的去质子化使受体与Hg 2+形成稳定的复合物。作为该中性Hg 2+络合物的应用,制备了与阳离子添加剂结合的阴离子选择电极,并显示出对碘化物阴离子具有提高的选择性的抗霍夫迈斯特选择性图案。电极的总选择性模式是我- > CLO 4 - > SCN - ≈溴- >水杨酸- > NO 2 - >氯- > NO 3 - »HCO 3 - > SO 4 2- >˚F - >ħ 2 PO 4 -。
