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