Mechanical Twisting a Guest by Light-Powered Molecular Pincers

Molecular machines” have not yet been used to mechanically manipulate a second molecule in a controlled and reversible manner.  We demonstrated that light-induced scissor-like conformational changes of one molecule can give rise to mechanical twisting of a non-covalently bound guest molecule.
