Abstract

The cis–trans isomerization of CH3S-Au-SCH3 driven by the tip of the scanning tunneling microscope is investigated at 77 K. CH3S-Au-SCH3 anchored on the Au(111) surface with the S–Au–S axis parallel to the substrate functions as a molecular switch due to the flipping of the CH3 groups. The bonding b...
