Abstract

Here we present the anion binding and anion transport properties of a series of calix[6]arenes decorated on their small rim with either halogen bond or hydrogen bond donating groups. We show that the halogen bond donating iodotriazole groups enable highly selective transport of chloride and nitrate anions, without transport of protons or hydroxide, at rates similar to those observed with thiourea or squaramide groups.

摘要

在这里，我们展示了一系列在其小边缘上用卤素键或氢键供体基团修饰的杯[6]芳烃的阴离子结合和阴离子传输性质。我们表明，卤素键供体碘三唑基团能够实现氯离子和硝酸盐阴离子的高选择性传输，而不会传输质子或氢氧化物，其传输速率与硫脲或脒基基团相似。
