Nonionic bolaamphiphiles and gemini surfactants based on carbohydrates were prepared and their aggregation behavior was studied. The gemini surfactants showed interesting aggregation behavior. When the spacer length was decreased from 10 to 6 methylene groups, the vesicles formed by these surfactants become less stable and turn into threadlike micelles upon cooling, thus giving the solution a viscous and viscoelastic character. This process is reversible.
