Resumen

A new ruthenium(II) porphyrin disulphide derivative, [Ru(Pds)(CO)], was obtained from ruthenium(II)(carbonyl)deuteroporphyrin(IX), [Ru(DPdc)(CO)] and cystamine. The interaction of this complex with nitric oxide was studied spectrophotometrically and a bathochromic shift of the charge transfer band and considerable change in the α and β bands of the complex were observed. According to the IR spectrum, the product of this interaction is [Ru(DmDP)(NO+)(NO2-)]. [Ru(Pds)(CO)] was then self-assembled on polycrystalline gold and characterized by X-ray photoelectron spectroscopy. [Ru(Pds)(CO)] was also self-assembled on gold electrode beads and its interaction with nitric oxide in aqueous solution was studied by cyclic voltammetry. A shift in the ruthenium redox process and a new irreversible cathodic peak at -0.59 V were observed, both indicating coordination of NO.
