Remote control in an eight‐component network commanded both the synthesis and shuttling of a [2]rotaxane via metal‐ion translocation, the latter being easily monitored by distinct colorimetric and fluorimetric signals. Addition of zinc(II) ions to the red colored copper‐ion relay station rapidly liberated copper(I) ions and afforded the corresponding zinc complex that was visualized by a bright sky blue fluorescence at 460 nm. In a mixture of all eight components of the network, the liberated copper(I) ions were translocated to a macrocycle that catalyzed formation of a rotaxane by a double‐click reaction of acetylenic and diazide compounds. The shuttling frequency in the copper‐loaded [2]rotaxane was determined to k₂₉₈=30 kHz (ΔH^≠=62.3±0.6 kJ mol⁻¹, ΔS^≠=50.1±5.1 J mol⁻¹ K⁻¹, ΔG^≠₂₉₈=47.4 kJ mol⁻¹). Removal of zinc(II) ions from the mixture reversed the system back generating the metal‐free rotaxane. Further alternate addition and removal of Zn²⁺ reversibly controlled the shuttling mode of the rotaxane in this eight‐component network where the ion translocation status was monitored by the naked eye.

[2]Rotaxane 的合成及其通过金属离子易位的穿梭的远程控制。

八组件网络中的远程控制通过金属离子易位指挥[2]轮烷的合成和穿梭，后者可以通过不同的比色和荧光信号轻松监测。将锌 (II) 离子添加到红色铜离子中继站中，迅速释放铜 (I) 离子，并提供相应的锌络合物，通过 460 nm 处的明亮天蓝色荧光可视化。在网络的所有八个组分的混合物中，释放的铜（I）离子被转移到大环中，该大环通过乙炔和二叠氮化合物的双击反应催化轮烷的形成。载铜[2]轮烷中的穿梭频率确定为k ₂₉₈ =30 kHz (Δ H ^≠ =62.3±0.6 kJ mol ^-1 , Δ S ^≠ =50.1±5.1 J mol ^-1  K ^-1 , Δ G ^≠ ₂₉₈ =47.4 kJ mol ^-1 )。从混合物中去除锌（II）离子使系统逆转，生成不含金属的轮烷。^{Zn 2+}的进一步交替添加和去除可逆地控制轮烷在该八组分网络中的穿梭模式，其中离子易位状态由肉眼监测。
