Description

Investigating charged molecules on insulating films is experimentally challenging. Atomic force microscopy, with single-electron sensitivity and capable of operating on insulating substrates, is a promising technique for such studies. Here we demonstrate multiple charge-state stabilization of molecules, induce intermolecular single-electron transfer and show that the charge state of a complex plays a role in its on-surface chemical reaction on multilayer insulating films. Moreover, we perform tunneling spectroscopy by using the atomic force microscope as a current meter, where we count single-electron tunneling events. This allows the quantification of the reorganization energy of a molecule on an insulating substrate.
