    The reversible binding of cations to self-assembled monolayers of (6-mercaptohexyloxy) methyl-12-crown-4 (1) and (6-mercaptohexyloxy)methyl-15-crown-5 (2) in aqueous solutions is reported. Binding of the electrochemically inactive cations can be monitored by cyclic voltammetry and impedance spectroscopy using Ru(NH3)6 2+/3+ as “reporter ions”. As a result of the high surface density of crown ether ligands sandwich complexes are probably formed, which accounts for the observed selectivities of the monolayer.
