建立控制大幅度亚分子运动的方法是开发通过分子水平的旋转运动发挥作用的人工装置的先决条件。在这里，我们证明了通过使用光将马来酰胺衍生的[2]轮烷异构化为相应的马来酰胺[2]轮烷，可以将其互锁组分的旋转速率加速>6个数量级。
Establishing methods for controlling aspects of large amplitude submolecular movements is a prerequisite for the development of artificial devices that function through rotary motion at the molecular level. Here we demonstrate that the rate of rotation of the interlocked components of fumaramide-derived [2]rotaxanes can be accelerated, by >6 orders of magnitude, by isomerizing them to the corresponding maleamide [2]rotaxanes by using light.
