M. in Reactions and Synthesis in Surfactant Systems; Ed.

Component concentrations at aggregate interfaces, e.g., water, halide ions, alcohols, are generally difficult to determine, especially in multicomponent systems. We have developed a novel chemical trapping reaction that is applicable to many of the components commonly used in studies of aggregate systems. Product yields from reaction of weakly basic ions and molecules with the aggregate bound arenediazonium ion, Figure 1 and Scheme 1, are proportional to the concentrations of ions and molecules ar the aggregate interface. The power of the method has been demonstrated in a variety of systems (see representative publications). Currently we are using the method to determine the affect of urea on aggregate structure, the distribution of alcohols and benzene in aqueous and reverse micelles and microemulsions and the hydration state of ionic and nonionic aggregates. The results should provide new insight in to the balance of forces that control the size, shape and phase states of these aggregated systems.
Chemical trapping reagent and a cartoon of a spherical cationic micelle in aqueous solution. The empty section faces illustrate the organization of amphiphiles in the aggregate; the micellar core filled by flexible tails of amphiphiles, their head groups (open circles) and hydrated counterions (filled circles). Space filling representations of the surfactant head and arenediazonium groups illustrate their similar size.
Dediazoniation mechanism. Spontaneous loss of nitrogen to form a reactive aryl cation that is trapped by available nucleophiles. Product yields from dediazoniations at aggregate interfaces, Figure 1, are used to estimate simultaneously, ion, molecule and, for the first time, water concentrations at aggregate surfaces.
