Abstract

Polysiloxanes bearing benzocrown-5 moieties have been synthesized and used as carriers for K+ and Na+ in supported liquid membranes. Although their lipophilicity is so high that leaching from the membrane is completely suppressed, their transport efficiency and selectivity can no longer be explained by a simple 1:1 crown:cation model. A more extensive multi-site model was developed that also takes into account cooperative and repulsive effects between adjacent binding sites. The transport properties were markedly influenced by the formation of 2:1 crown:K+ complexes. No evidence was found for repulsive interactions.
