摘要

Catenanes are molecules made of two or more interlocked rings,and rotaxanes are composed of rings threaded onto axles that look like dumbbells because they are terminated by stoppers large enough to prevent unthreading (Figure 1)[1].[n]Catenanes are constituted by n interlocked rings,whereas [n]rotaxanes are made of n-m rings and m dumbbell components.Both constitute the prototypical molecular objects featuring the so-called "mechanical bond".
