A molecular shuttle consisting of a dibenzo-24-crown-8 macrocycle and an axle with two degenerate peripheral triazolium stations, a central dibenzyl ammonium station, and two anthracenes stoppers was exposed to 2-cyano-2-phenylpropanoic acid as a chemical fuel. Protonation/deprotonation of the amine reversibly switches the rotaxane from a static and little emissive to a dynamic fluorescent shuttling device, the latter exhibiting rapid motion (15 kHz at 25 °C). Four fuel cycles were run.
一种由二苯并-24-冠-8 大环和一个带有两个简并的外围三唑基站、一个中央二苄基铵站和两个蒽塞子的轴组成的分子梭子被暴露于 2-氰基-2-苯基丙酸作为化学燃料。胺的质子化/去质子化可逆地将轮烷从静态和低发光状态切换为动态荧光穿梭装置，后者表现出快速运动（25°C 时为 15 kHz）。进行了四个燃料循环。
