A 'Molecular Pivot-Hinge' Based on the pH-Regulated Intramolecular Switching of Pt-Pt and pi-pi Interactions

摘要

The use of explicit conformational features and intra- and intermolecular interactions in specifically designed organic,coor-dination/organometallic,and supramolecular systems to mimic mechanical motions in the macroscopic world is of great research and applied interest.Elegant molecular devices such as molecular clips,gears,hinges,ratchets,rotors,scissors,shuttles,switches,and tweezers with different supramolecular architectures have been actively explored in recent years.
