✦ Synopsis
Membrane Selectivity and Syntheses of Ionophores for Li^+^. Stability Constants in Ethanol
Electrically 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.

Different lipophilic β‐diketones have been prepared. Some preferably transport Mg^2+^ and Ca^2+^ through PVC‐based liquid membranes when a pH‐gradient is applied across the membrane. A theoretical model is presented that allows a description of potentiometrically determined ion selectivities as well
