The research on the vesicle formation and transformation in novel Gemini surfactant systems

Three new types of Gemini amphiphiles (N,N′-bis-(4-decyloxybenzylidene)-ethane-1,2-diamine, N,N′-bis-(4-decyloxy-2-hydroxybenzylidene)-ethane-1,2-diamine, and (N,N′-bis-(4-decyloxy-2-hydroxybenzylidene)-ethane-1,2-diamine)copper(II) were synthesized. Their aggregation behaviors were studied by TEM observation and monolayer experiments. It was found that the vesicle formation and transformation can be adjusted by molecular structure, pH value and the concentration of Cu2+ in these surfactant systems.
