Conformational changes of single molecules induced by scanning tunneling microscopy manipulation: A route to molecular switching
A detailed experimental and theoretical investigation of the processes involved in the
manipulation of individual specially designed porphyrin-based molecules by scanning
tunneling microscopy at low temperature is presented. On a stepped Cu (211) surface, the
interaction between tip and molecule was used to locally modify in a reversible way the
internal configuration of a single molecule, thus drastically changing the tunneling current
passing through it. Model calculations confirm that this manipulation realizes the principle of …

Abstract
A detailed experimental and theoretical investigation of the processes involved in the manipulation of individual specially designed porphyrin-based molecules by scanning tunneling microscopy at low temperature is presented. On a stepped Cu (211) surface, the interaction between tip and molecule was used to locally modify in a reversible way the internal configuration of a single molecule, thus drastically changing the tunneling current passing through it. Model calculations confirm that this manipulation realizes the principle of a conformational molecular switch.
