[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+ / TTF2+ ). Switching
由环双(百草枯-对亚苯基)四阳离子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构成的[2]环烷中的机械开关可以是化学或电化学投掷。中性TTF单元以还原态位于四阳离子环烷“内部”,而在氧化物种(TTF + / TTF 2+)中“与其并列” 。在还原态(I 4+)和氧化态(I 5+(I 6+))之间切换时会发生剧烈的颜色变化。
