## Abstract The preparation of a series of nonβcyclic, uncharged ligands able to selectively complex alkali and alkaline earth metal cations is described. These molecules are designed to be used as carriers for cations through membranes. Some of the compounds show high Ca^2+^ and Na^+^ selectivity,
Potentiometric selectivities for alkali metal, alkaline earth metal and ammonium ions for a series of N,N-dialkyl .qwz-( R)dibenro-16-crown-5-oxyacetamides in solvent polymeric membrane electrodes are determined. For N,N-dipentyl sym-(R)dibenzo-16-crown-5-oxyacetdmides, the Na+/K ' selectivity incre
