Efficient transport of alkali and ammonium ions by proton-ionizable ester crowns containing 1H-pyrazole units. Symmetric complexing behaviour towards europium observed by 13C n.m.r. spectroscopy

Pilar Navarro  and  M. Isabel Rodríguez-Franco  

Abstract

The alkali and ammonium ion transport properties in a H2O–CHCl3–H2O bulk liquid membrane system have been evaluated for ester crowns containing 1H-pyrazole units, and their symmetric complexing behaviour towards 1,1,1,2,2,3,3-heptafluoro-7,7-dimethyloctane-4,6-dionatoeuropium(III) observed by 13C n.m.r. spectroscopy; crown (4)(38-membered ring) is an efficient carrier of K+ and NH4+ ions.
