Resumen:
Osmium pyridine-bipyridine redox centers have been tethered to Au electrodes by chemicalmodification through AuS and AuC bonds respectively. 4-mercapto benzoic acid and thereduction product of the aryl diazonium salt of 4-amino benzoic acid were reacted on Ausurfaces, with further post-functionalization by chemical reaction of the osmium complexamino-pyridine derivative with the surface carboxylates. The resulting modified Au surfaceswere characterized by polarization modulated infrared reflection absorption spectroscopy(PM-IRRAS), scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy(XPS), resonant raman spectroscopy and cyclic voltammetry.
