Abstract: Because of their possible relevance as model compounds of cation transport across membranes open chain “crown” ether molecules and pyridinophane cryptands have been synthesized in order to study their interaction with sodium and potassium ions. The stoichiometry and stability of the Na+ and K+ complexes were determined spectrophotometrically, and the kinetics of complex formation was investigated by ...
