Hydrogen-bonding interactions between suitable phenols and the head group of the twin-tailed anionic surfactant sodium bis(2-ethylhexyl)sulfosuccinate (AOT), form the basis for a novel class of organogels. The gels are novel in that very small quantities of these low molecular weight solutes are sufficient to cause gelation. Previous work has shown that the gel-forming propensity of the phenol is...
The luminescence of CdS nanoparticles suspended in dry AOT reversed micelles is quite intense but is quenched by water and even more effectively by thiol-containing compounds. Stern-Volmer plots provide information about the quenching efficiencies of various compounds. Of particular interest is 4-hydroxythiophenol which interacts strongly with the surfactant headgroups and thereby partitions...
