Rotaxanes are mechanically interlocked molecules consisting of a dumbbell-shaped molecule threaded through a macrocycle, held together by bulky end groups that prevent disassembly. These structures are pivotal in the development of molecular machines and nanotechnology due to their unique mechanical properties and potential for controlled movement.

Mechanically interlocked molecules are a class of molecules that are connected through their topology rather than covalent bonds, allowing for restricted motion and unique functional properties. These complex structures have potential applications in molecular machines, nanotechnology, and smart materials due to their ability to undergo controlled conformational changes.
