Building up functional 2D supramolecular assemblies requires the unit blocks involved in their bottom up formation to be already complex. In the construction of the tailored nanostructures, different approaches can be adopted in order to circumvent the limitations of the traditional wet chemical methods [1,2]. Among them, specifically the Electrospray Deposition (EDS) technique emerges as suitable pathway to explore the adsorption of organic compounds with higher structural complexity [3].
In the present work, we report the adsorption of complex molecules on a noble metal surface. Our study focus on the influence of intermolecular and surface-molecule interactions in the observed assemblies. The deposition of the molecules is carried out by HV-EDS. Furthermore, visualization of the molecules is achieved by means a home-made Atomic Force Microscopy (AFM) set-up, in non-contact operation mode.
