In the last few decades conjugated organic polymers and oligomers have attracted a broad interest due to their excellent electronic and
weak intermolecular van der Waals forces and molecule–substrate interactions, as well as intermolecular hydrogen bonding in the case of functionalizedoligothiophenes [15][16][17]. The typical flat metallic substrates (HOPG, Au(111), Ag(111), etc.) employed in STM differ from the ITO electrodes used in
molecular dipole moments.
