Unravelling the Shuttling Mechanism in a Photoswitchable Multicomponent Bistable Rotaxane

摘要

The bottom-up construction and operation of multicompo-nent molecular systems capable of performing specific,directional mechanical movements under the action of a defined energy input-namely,molecular machines-are currently under extensive investigation.This research not only constitutes a fascinating challenge in the field of nanoscience,but could also find applications in areas such as material science,diagnostics,and medicine However,despite the large number of molecular machines that have been constructed,only a rather limited number of studies are available that are aimed at elucidating the details of the working mechanism and the factors that influence the molecular motions in this kind of systems.
