Motor proteins are ubiquitous in nature and are at the basis of many biological processes, such as, e.g., DNA replication, 1 muscle contraction and ATP synthesis. These are complex molecular systems composed of molecular sub-parts that interact via non-covalent interactions, and move with respect to each other generating motion upon absorption of energy or external stimuli. For the last decades, one of the biggest challenges for chemists and physicists has been to design and synthesize artificial molecular machines (AMMs) with controllable movements, mimicking nature's technology. Great efforts in this field have produced a large variety of, e.g., mechanically interlocked molecules (MIMs), such as, to mention a few, catenanes, rotaxanes, and molecular shuttles, and have led to the Nobel Prize for Chemistry awarded to Feringa, Sauvage and Stoddart in 2016.
