Chirality Change of Chloronitrobenzene on Au(111) Induced by Inelastic Electron Tunneling

Chirality chameleon: Inelastic electron tunneling manipulation can be used to change a single chloronitrobenzene (ClNB) molecule, randomly adsorbed on Au(111), into its desired enantiomeric form (r or l, see STM images and ball-and-stick representation) and to vary its rotational orientation.

Description
Summary:Chirality chameleon: Inelastic electron tunneling manipulation can be used to change a single chloronitrobenzene (ClNB) molecule, randomly adsorbed on Au(111), into its desired enantiomeric form (r or l, see STM images and ball-and-stick representation) and to vary its rotational orientation. The different threshold voltages for chirality change (260 mV) and rotation (380 mV) allow these processes to be induced separately.
