Ordered molecular nanostructured films (see figure) are obtained by exploiting the molecular-induced substrate faceting transition, following a very simple protocol. The obtained nanostructures show univocal alignment and quite good homogeneity, and the pattern periodicity can be controlled in the process. The stepped structure of the vicinal metallic substrate has a key role in the film production mechanism.
