We describe self-assembled monolayers of novel halogen-bonding and hydrogen-bonding foldamer receptors capable of selectively recruiting perrhenate, iodide and thiocyanate in water. Unprecedented anion sensing via impedance-derived capacitance spectroscopy enables subsequent sensitive and selective anion detection without the need for a redox probe. Importantly, the sensing of any anion should be possible using this novel electrochemical approach.
我们描述了新型卤键和氢键折叠体受体的自组装单分子层，它们能够在水中选择性地捕获高铼酸盐、碘化物和硫氰酸盐。通过基于阻抗的电容光谱进行的前所未有的阴离子传感，无需氧化还原探针即可实现后续灵敏且选择性的阴离子检测。重要的是，使用这种新型电化学方法应该能够检测任何阴离子。
