Researchers demonstrate current-driven molecular rotor with enhanced conductance
Researchers report a helicene-based molecular machine whose rotation is driven by electric current and changes its conductance.
Researchers report in Nature that a helicene molecule suspended between electrode tips rotated in a preferred direction when voltage was applied. They said reversing voltage polarity reversed the direction of rotation.
The study reports that conductance increased once rotation began and that changing the molecule's length shifted the voltage threshold. The paper describes the result as a prototype molecular machine.
