Ion-selective Response of the Azacrown-terminated Self-assembled Monolayer Formed on a Gold Electrode

抄録

Thiol derivatized aza-15-crown-5-ether (15C5) was synthesized and modified on a gold electrode surface as the self-assembled monolayer. The effects of the alkali metal ions on the CV response of the Fe(CN)₆³⁻ probe ion at the modified electrode were investigated with changing alkali metal ion. The CV response was decreased in the order of Rb⁺≥K⁺>Li⁺≫Na⁺. The results are discussed in relation to the interaction between the crown ring and the alkali metal ions.
