Amplification upon polymerization of the electrochemical anion sensing properties of an amidoferrocene monoreceptor molecule

Oxidative electropolymerization of pyrrole-substituted monoamidoferrocene 1 yields redox polymer films showing marked electrochemical sensing properties towards H2PO4− and ATP2− anions in organic electrolytes, as demonstrated by differential pulse voltammetry experiments. This behavior contrasts with the poor sensing properties of monomer 1.
