New type of surfactant: the annelides. Characterization of organized metal ion assemblies obtained by cationic complexation at the micelle
The first members of a new class of amphiphiles, the annelides, consisting of a macrocyclic polar head able to include spherical or quasispherical cations and a long paraffinic tail, have been synthesized and characterized. They are shown to behave successively as nonionic or ionic surfactants depending on the presence of a complexable cation. The geometric parameters of the metal ion assemblies obtained by micellization are thoroughly determined by various physical methods including light scattering. The intersite degree of organization and the cooperative effect at the micellar interface are evaluated. The cationic complexation at the micellar subsurface is characterized. A convenient method for determining the local electrostatic properties of the interfacial region is exposed. 68 references.
