Abstract

Abstract The preparation of a series of non-cyclic, uncharged ligands able to selectively complex alkali and alkaline earth metal cations is described. These molecules are designed to be used as carriers for cations through membranes. Some of the compounds show high Ca 2+ and Na+ selectivity, respectively, in liquid membrane electrodes.
