Abstract GC/OligoThiophene/Ag(NP) hybrid interfaces are synthesized and characterized: GC is the glassy carbon surface, OligoThiophene stands for a bithiophene moiety (or 4-Br-Bithiophene grafted interlinked polymer), Ag(NP) stands for silver nanoparticles. The hybrid interface preparation is a three steps procedure: first the electrode surface is functionalized through the combination of electrochemical assisted grafting (under reduction regime) and polymerization (under oxidation regime), then silver nanoparticles are chemisorbed by dipping. AFM and TEM images have been recorded to investigate the morphology and chemical composition of the Ag(NP). FeII/FeIII cyclic voltammetry, Zn underpotential deposition (UPD) , XPS, LA-ICP-MS and Raman techniques were exploited to characterize both the GC/OligoThiophene and GC/OligoThiophene/Ag(NP) interfaces. Theoretical calculation, at the B3LYP/6-311G** level of the theory, allowed to rationalize the electroreduction mechanism and the Raman results.
