Abstract

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.
