英文摘要	A detailed study of the reverse vesicles formed by a salt-free catanionic surfactant system in toluene wascarried out by confocal fluorescence microscopy observations, dye-solubilizing tests, UV–vis measure-ments and cryo-TEM observations. When tetradecyltrimethyl ammonium laurate (TTAL) and lauric acid(LA) were mixed in the binary solution of water and toluene, reverse vesicular phase formed spon-taneously. The reverse vesicular phase is quite stable and can be labeled with fluorescent dyes forsubsequent confocal fluorescence microscopy observations. However, the reverse vesicles were found tohave smaller sizes (<1 µm) and undergo structural evolutions in a much shorter time scale compared tothose formed by the same surfactant mixture in cyclohexane, as shown in a previous report [19]. Withextended observation time, interesting intermediate structures were observed including onions, sheetsand cellular networks. The structural evolution pathways were deduced and the possibly influencingfactors were discussed. Dye-solubilizing tests showed the ability of the reverse vesicles to accommodatedye molecules is smaller compared to those in cyclohexane. Besides, cryo-TEM observations were appliedto probe the morphology of the reverse vesicles.
