The vesicle bilayer acts as a barrier of medium strength for water-soluble, non-ionic organic compounds. Sucrose solutions, for example, were applied as contrast agents in the light microscopy of stearic acid vesicles ". It took hours for the carbohydrate to penetrate this barrier. Efflux rates of radioactive sucrose were measured in cationic vesicles in the presence of different counterions. For this purpose, external sucrose was removed by ultrafiltration through Nucleopore polycarbonate with 0.4, 0.2 and 0.1 xm pores. The efflux rates were then determined by dialysis methods. In the case of dihexadecyldimethyl-... 

The possibility of complexation of inorganic salts, as well as of ionic and non-ionic organic compounds, can be explained by the dipole effect of the C-O bond in the polyether ring. Other hetero atoms such as nitrogen or sulfur may also act as donor atoms. The selective complexation of a specific cation, which is always associated with an anion because of electroneutrality, depends on the number and position of the hetero atoms.
