A1H NMR study of 1,4-bis(N-hexadecyl-N,N-dimethylammonium)butane dibromide/sodium anthranilate system: spherical to rod-shaped transition.
The effect of addition of sodium anthranilate to 5 mM micellar solutions of gemini surfactant 1,4-bis(N-hexadecyl-N,N-dimethylammonium)butane dibromide is investigated by1H NMR. The solubilization site of anthranilate anion near the micellar surface is inferred. In the micelles, the An-ions intercalate among the surfactant headgroups producing morphological changes.
