With the aid of pH variation, fine control electrostatic interaction and hydrogen bond was realised in mixed system oleic acid diethylenetriamine. Owing to transformation intermolecular interactions, corresponding building blocks changed from DETA2+@2OA−via coexistence DETA@2OA− DETA+@OA− DETA@2OA−. Therefore, diverse microstructures phase behaviors this surfactant were obtained at different values. It is found that efficient for tailoring self-assembled structures cationic–anionic system, including vesicles, bilayers, networks formed by aggregated vesicles fibers.
