Light induced micelle to vesicle transition in an aqueous solution of a surface active ionic liquid

A new surface active ionic liquid 4-butylazobenzene-4′-hexyloxy-trimethyl-ammoniumtrifluoro-acetate (BHATfO) was synthesized to achieve light-responsive and reversible micelle–vesicle transformation, which was verified by means of UV-spectroscopy, surface tension, conductivity, dynamic light scattering and transmission electron microscopy.
