In this work, we designed and synthesized a special axle guest hexyldimethyl(ferrocenylmethyl)ammonium ( ) bromide. The binding interactions of and its oxidized form with cucurbit[7]uril (Q[7]) and cyclohexanocucurbit[6]uril (Cy6Q[6]) were investigated by H NMR, cyclic voltammogram, and isothermal titration calorimetry techniques. Our data indicate that both hosts Cy6Q[6] and Q[7] can form stable [2]pseudorotaxanes with in their different redox states. Most importantly, the combination and dissociation of the hosts with the guest as well as the binding location can be controlled by electrochemical means, which develops a special molecular switch and selector.
在本工作中，我们设计并合成了一种特殊的轴客体己基二甲基（二茂铁基甲基）溴化铵（ ）。通过核磁共振氢谱（H NMR）、循环伏安法和等温滴定量热法技术研究了 及其氧化形式 与葫芦[7]脲（Q[7]）和环己基葫芦[6]脲（Cy6Q[6]）的结合相互作用。我们的数据表明，主体Cy6Q[6]和Q[7]在其不同氧化还原状态下都能与 形成稳定的[2]准轮烷。最重要的是，主体与客体的结合和解离以及结合位置可以通过电化学手段进行控制，这开发了一种特殊的分子开关和选择器。
