Synthesis and Electrochemical Behavior of a New Water Soluble Ca2+-selective Ionophore Based on Calix[4]arene-triacid-monoquinone

A new water-soluble calix[4]arene-triacid-monoquinone 3 has been synthesized and its ion binding properties in aqueous solution were investigated by means of voltammetry and UV-visible spectrophotometry. The electrochemical behavior of 3 is dependent on the concentration of Ca2+ ion rather than that...

Description
Summary:A new water-soluble calix[4]arene-triacid-monoquinone 3 has been synthesized and its ion binding properties in aqueous solution were investigated by means of voltammetry and UV-visible spectrophotometry. The electrochemical behavior of 3 is dependent on the concentration of Ca2+ ion rather than that of other alkaline earth metal ions as well as alkali metal cations. The selective response toward Ca2+ was achieved even in the presence of a large excess ( > 1000-fold) of interfering Na+ ion.
