✦ Synopsis

Abstract

A chiral macrocyclic crown ether exhibits an enantiomer‐selectivity of 2.6 for α‐phenylethylammonium ion when incorporated in solvent polymeric membranes. The sequence of selectivity of these membranes clearly differs from that of lipophilicity for the different biogenic ammonium ions studied, indicating a significant structural contribution.
