摘要：

Based on complex chemical considerations, lipophilic diamide derivatives have been designed and synthesized as ionophores for liquid membrane electrodes. The structure-selectivity studies revealed that the majority of the ligands exhibit calcium ion selectivity except the compound bis-N,N-dicyclohexyl-malonamide. The latter has an almost equal selectivity for Ca2+ and Mg2+ and sufficiently rejects sodium ions, thus it lends itself to water hardness measurements.
