A mechanical switch in a [2]catenane, made up of a cyclobis(paraquat-p-phenylene) tetracation interlocked with a macrocyclic polyether containing a redox-active tetrathiafulvalene (TTF) unit and a 1,5-dioxynaphthalene ring system, can be thrown either chemically or electrochemically. The neutral TTF unit resides "inside" the tetracationic cyclophane in the reduced state and "alongside" it in the oxidized species (TTF / TTF ). Switching between the reduced (I ) and oxidized state (I (I )) is accompanied by a dramatic color change.
在一种[2]轮烷中的机械开关，它由与包含氧化还原活性四硫富瓦烯（TTF）单元和1,5-二氧萘环系统的大环聚醚互锁的环双（百草枯对亚苯基）四阳离子组成，可以通过化学或电化学方式进行切换。中性TTF单元在还原态时位于四阳离子环番“内部”，在氧化态物种（TTF/TTF）中则“ alongside”它。在还原态（I）和氧化态（I（I））之间切换伴随着显著的颜色变化。 （注：这里的“alongside”可能翻译得不是特别准确，因为在化学语境中可能有更合适的术语来描述其位置关系，但按照要求进行了直接翻译。）
