A new bis(phosphine) amide linked ferrocene ligand [Fe{η-C5H4CONH(CH2)3PPh2}2] and molybdenum, chromium, rhodium and ruthenium transition metal chelated receptors of it have been prepared. Proton NMR anion-binding investigations revealed that in general the combination of the Lewis acid transition metal centre and the ferrocene amide moiety enhances the strength of anion binding. Electrochemical studies showed all receptors can electrochemically sense halide, dihydrogenphosphate and hydrogensulfate anions via significant cathodic perturbations of the respective ferrocene and transition metal oxidation wave. |
