A rotaxane is a mechanically interlocked molecular architecture consisting of a dumbbell-shaped molecule that is threaded through a macr 1 ocycle (a cyclic molecule with a large ring). The ends of the dumbbell-shaped molecule are bulky groups that prevent the macrocycle from slipping off. Rotaxanes are intriguing molecules with potential applications in molecular machines, switches, and sensors.

轮烷是一种机械互锁的分子结构，由穿过大环（具有大环的环状分子）的哑铃形分子组成。哑铃形分子的末端是庞大的基团，可防止大环滑落。轮烷是具有吸引力的分子，在分子机器、开关和传感器中具有潜在的应用。
