## Abstract The preparation of a series of nonโcyclic, 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,
The leaching process of lipophilic anionic additives (e.g., tetraphenylborates) from neutral carrier based membranes into an aqueous sample is quantified. While the necessary lipophilicity (i.e., equilibrium partition coefficient) of the additive for a certain lifetime of the sensor is identical to
