Molecular switches change their structural, electronic and/or optical properties upon external stimuli and are envisioned as essential building blocks for the realization of nano-circuits . In this project we use low temperature scanning tunneling microscopy (LT-STM) to study molecules on surfaces with resolutions down to the subnanometer scale. Additionally to providing local information in real space, LT-STM can be used for local tip induced manipulations of molecules, as translation or conformational switching. The unification of these two advantages makes STM a powerful tool for the study of molecular switching processes [2,3].
