The design, synthesis and self-assembled study of a new class of benzene-derived tripod facial amphiphiles are reported. The synthetic route chosen based on a central mesitylene as scaffold allows easy tuning of lipophilic and hydrophilic groups and thus control of the tensioactive properties of these new surfactants. This new class of surfactants exhibits three glucose moieties as the hydrophilic polar head and three hydrocarbon chains each having 3 to 7 carbons as the lipophilic part. These tripod facial amphiphiles exhibit well-defined tensioactive and aggregative properties. Their critical aggregation concentration, their particle size in water (less than 20 nm), and their aggregation behavior are closely linked to the nature of their lipophilic chains and can therefore be easily modulated.
synthesized for supramolecular binding study of fullerenesC60 and C70. Binding constants for C60 in chlorobenzene, toluene, toluene–CH2Cl2 and CS2 have been calculated for different hosts and a direct structure–affinity relationship has been established. As predicted, receptors with two exTTF moieties (1, 3 and 4) have demonstrated higher binding abilities toward C70 than C60. Depending on the linker used
A great variety of mono- and polytopicβ-cyclodextrinhosts have been easily synthesized by using the CuI-catalyzed azide–alkyne cycloaddition reaction. Of particular interest for their multibinding properties, dimeric and trimeric CD compounds were obtained by “clicking” mono-6-azido-β-cyclodextrin derivatives with flexible or rigid dialkynyl spacers. The reaction is general, high-yielding for some
