Abstract

Redox responsive macrocyclic ligands can be used for the recognition of charged guest molecules and so are of importance for potential new molecular sensory devices. Systems are reported that enable the electrochemical recognition of various cations and anions. Tripodal cobalticinium and ferrocene ionophores electrochemically recognize H2PO4 in the presence of excess HSO4 and Cl anions.
