Abstract
Based on complex chemical considerations, lipophilic diamide derivativ es have been designed and synthesized as ionophores for liquid membran e electrodes. The structure-selectivity studies revealed that the majo rity of the ligands exhibit calcium ion selectivity except the compoun d bis-N,N-dicyclohexyl-malonamide. The latter has an almost equal sele ctivity for Ca2+ and Mg2+ and sufficiently rejects sodium ions, thus i t lends itself to water hardness measurements.
