A unique ionic liquid with amphiphilic properties that can form reverse micelles and spontaneous unilamellar vesicles.

Catanionic surfactants: the synthesis of a new surfactant ionic liquid with unique properties is described. The formation of reverse micelles in benzene and large unilamellar vesicles, formed spontaneously without the help of any mechanical of chemistry methods, in water is demonstrated by using dynamic light scattering and small-angle X-ray scattering techniques.
