<p>A process of electrochemically reducing an aromatic diazonium salt on a substrate surface, the process comprising the steps of: i) contacting the substrate surface with a solution comprising the aromatic diazonium salt in an aprotic medium; and ii) applying a constant negative potential to the substrate relative to a reference electrode which is also in contact with the aromatic diazonium salt. Also claimed is a substrate obtainable by this process and the use of the substrate for detection of a pH change.</p> |
