A ferrocene appended rotaxane is prepared by chloride anion templation and ring closing metathesis. Upon removal of the chloride template, the rotaxane is demonstrated to be selective for chloride over more basic oxoanions by (1)H NMR spectroscopy and electrochemistry, in marked contrast to an acyclic analogue--the first example of a solution based redox-active interlocked host system capable of the electrochemical recognition of anions.
通过氯离子模板化和关环复分解反应制备了一种二茂铁取代的轮烷。在除去氯离子模板后，通过（1）H NMR 光谱和电化学方法证明轮烷对氯离子具有选择性，而对更碱性的含氧阴离子则没有选择性，这与非环状类似物形成鲜明对比——这是首个基于溶液的氧化还原活性互锁主体系统能够电化学识别阴离子的例子。
