  Dicarboxylic acid diamides having the formula I ##STR1## wherein the radicals R are selected from hydrogen, alkyl, alkenyl and alkynyl with up to 20 carbon atoms, have a high selectivity for lithium ions over other alkali metal ions and alkaline earth metal ions. Ion selective membranes and ion selective coatings as well as ion selective test devices, like e.g. test strips, which contain said compounds of formula I as ion selective component, can be used for the determination of lithium ions in liquid media. Said membranes and test devices are also suited for the determination of the concentration of lithium ions in biological fluids in which low concentrations of lithium ions and high concentrations of sodium ions are present, like the corresponding determination in blood serum or whole blood. The ion selective membranes have a period of life of several months even if they are frequently contacted with blood serum or blood. Lithium complexes of the dicarboxylic acid diamides of formula I were prepared in crystalline form and the new carboxylic acid diamides of formula I were prepared by etherifying the corresponding diols.

  具有以下式I的二羧酸二酰胺具有高选择性，其中基团R从氢、烷基、烯基和炔基中选择，碳原子数最多为20个，对锂离子优于其他碱金属离子和碱土金属离子。离子选择性膜和离子选择性涂层以及离子选择性测试装置，如测试条，其中含有上述式I化合物作为离子选择性组分，可用于液体介质中锂离子的测定。所述膜和测试装置还适用于测定生物液体中锂离子的浓度，在其中存在低浓度的锂离子和高浓度的钠离子，如血清或全血中的相应测定。即使经常与血清或血液接触，离子选择性膜的使用寿命可达数月。通过结晶形式制备了具有式I的二羧酸二酰胺的锂络合物，并通过醚化相应二醇制备了新的式I的羧酸二酰胺。

  Membrane Selectivity and Syntheses of Ionophores for Li+. Stability Constants in EthanolElectrically neutral, lipophilic complexing agents were prepared which induce Li+ selectivity in solvent polymeric membranes. Stability constants for group IA and IIA cations of one such ligand in ethanol have been determined. The selectivity behaviour of this ligand in membranes as well as in extraction systems is studied and discussed in terms of model considerations.
