The chloride anion templated synthesis of an electrochemical anion sensory interlocked host system, prepared by the integration of redox-active 1,2,3,4,5-pentaphenylferrocene stopper groups into the structure of a rotaxane capable of binding anionic guests is described. Extensive (1)H NMR and electrochemical titration investigations were used to probe the anion recognition and sensing properties of the rotaxane, compared to the axle and model system components. A characteristic electrochemical response was observed for chloride binding by the rotaxane, which was attributed to the topologically constrained cavity of the interlocked host molecule.
氯离子模板合成电化学阴离子感应互锁主体系统，通过将氧化还原活性的 1,2,3,4,5-五苯基二茂铁止动基团整合到能够结合阴离子客体的轮烷结构中制备得到。采用（1）H NMR 和电化学滴定研究来探测轮烷与轴和模型体系组分相比的阴离子识别和传感特性。观察到轮烷与氯离子结合的特征电化学响应，这归因于互锁主体分子的拓扑约束腔。
