Catenanes

Catenanes are molecules composed of two or more ring-shaped structures interlinked like links in a chain. Unlike typical molecules where atoms are connected in a fixed arrangement, catenanes are characterized by their mechanically interlocked rings, which can slide or rotate relative to each other without breaking the bonds. They are often studied in chemistry for their unique properties and potential applications in molecular machines, sensors, and nanotechnology. Their design demonstrates how molecules can be engineered to mimic macroscopic mechanical systems at a nanoscale, providing insights into creating dynamic and functional molecular architectures.
