Neutral XB [2]rotaxanes containing remarkably potent XB axle components including a novel 4,6-dinitro-1,3-bis-iodotriazole motif are constructed via a discrete chloride anion template directed synthesis. Quantitative 1H NMR halide anion titration studies in competitive aqueous-organic solvent mixtures reveal the XB [2]rotaxanes display pronounced anti-Hofmeister halide anion recognition selectivity for
通过离散氯阴离子模板定向合成,构建了含有非常有效的 XB 轴组分(包括新型 4,6-二硝基-1,3-双碘三唑基序)的中性 XB [2]轮烷。在竞争性水-有机溶剂混合物中进行的定量1 H NMR 卤化物阴离子滴定研究表明,与碘化物相比,XB [2]轮烷对氯离子表现出明显的反霍夫迈斯特卤化物阴离子识别选择性。
