Abstract
Redox-driven mechanical movement, which has been achieved for a liquid-crystalline (LC) bistable [2]rotaxane in the LC phase, is accompanied by obvious electrochromism (electrochemically induced changes in color) of the material. The dumbbell-shaped LC [2]rotaxane with redox-active moieties, which interlocks with an ionic macrocycle, forms ordered redox-active condensed states.
摘要
氧化还原驱动的机械运动已在液晶（LC）双稳态[2]轮烷的 LC 相中实现，同时伴随着材料明显的电致变色（电化学诱导的颜色变化）。具有氧化还原活性部分的哑铃形 LC [2]轮烷与离子大环互锁，形成有序的氧化还原活性凝聚态。
