摘要：

The colloid stability of mixed vesicles composed of two components, a crown ether with a long hydrocarbon chain and a phospholipid, against bolaform surfactants was studied. The critical coagulation concentration of primary ammonium ions of the bolaform for the vesicle is lower than that of corresponding quaternary ammonium ions, which can be attributed to the affinity difference between the two types of terminal ionic groups for the crown ether. The steric bulky effect of bolaform ions on the screening potentiality against the surface charges is negligible, but the hydrophobic interaction of a hydrocarbon chain connecting the two terminal ionic parts of the surfactants with the vesicle surface plays a significant role in the vesicle coagulation. © 1990.
