WebOct 18, 2016 · In molecules, the mechanical bond is not shared between atoms—it is a bond that arises when molecular entities become entangled in space. Just as supermolecules are held together by supramolecular interactions, mechanomolecules, such as catenanes and rotaxanes, are maintained by mechanical bonds. WebWhereas biology has perfected its machines over billions of years of evolution, chemists keen to imitate these structures are just getting started. In the late 1980s, researchers started building assemblies of molecules that contain mechanically interlocked components, where two or more parts can’t be separated without breaking a covalent bond. WebArtificial molecular machines have captured the imagination of scientists and nonscientists alike for decades now, given their clear potential to transform and enhance all aspects of human life.
