Recognition of the dihydrogenophosphate anion on a gold electrode derivatized with an amidoferrocenylalkylthiolate ligand

A dialkyl disulfide derivative with an amidoferrocenyl termini was synthesi zed and coordinated as an alkylthiolate ligand to the surface of a gold ele ctrode which was shown by cyclic voltammetry. This derivatized electrode be haved as an electrochemical redox sensor allowing the recognition of the di hydrogenophosphate anion. (C) Academie des sciences/Elsevier, Paris.
