Syntheses and Properties of New Pendant‐armed Calix[4]arene Derivatives as Cesium Selective Ionophore

Syntheses and Properties of New Pendant‐armed Calix[4]arene Derivatives as Cesium Selective... Two new pendant‐armed calix[4]arene derivatives 5 and 6 have been synthesized. The study of alkali metal picrates extraction indicates that both compounds show preference of cesium cation, compound 6 in 1,3‐alternate conformation has better extractibility for Cs+ than compound 5. The coordination behavior of compound 6 with cesium cation was studied by 1H NMR spectroscopy. The Cs+ selective electrode based on compound 6 exhibits a linear, near Nernstian response characteristics, the slope is 56.4 mV/decade in me concentration range of 10−4—10−1 mol/L, the selectivity coefficient (logKpotCs.Na) is −3.39. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Chinese Journal of Chemistry Wiley

Abstract

Two new pendant‐armed calix[4]arene derivatives 5 and 6 have been synthesized. The study of alkali metal picrates extraction indicates that both compounds show preference of cesium cation, compound 6 in 1,3‐alternate conformation has better extractibility for Cs+ than compound 5. The coordination behavior of compound 6 with cesium cation was studied by 1H NMR spectroscopy. The Cs+ selective electrode based on compound 6 exhibits a linear, near Nernstian response characteristics, the slope is 56.4 mV/decade in me concentration range of 10−4—10−1 mol/L, the selectivity coefficient (logKpotCs.Na) is −3.39.
