Abstract
Transport of alkali-ions across black lipid membranes (BLM) formed fro m cationic and anionic, double-chain amphiphiles was characterized by the charge pulse relaxation technique. Amphiphiles containing an ether linkage in the alkyl tail portion displayed enhanced transport rates for sodium and potassium ions, while such selectivity is not observed for the related amphiphile without the ether linkage.
