제목 Micellar and vesicular nanoassemblies of triazole-based amphiphilic probes triggered by mercury(ll) ions in a 100% aqueous medium
초록 Amphiphilic molecules based on triazole-based aromatic segment and hydrophilic tri(ethylene oxide) were easily synthesized using facile Click chemistry which act as a fluorescent turn-off Hg2+-chemoprobe in an aqueous solution. Interestingly, it revealed that the metal-binding process of amphiphiles can induce the nano-assemblies even below the CMCs, and the binding stoichiometry affects the morphologies of the resultant nanostructures. The self-assembling behaviour of the amphiphiles was examined by UV-Vis and fluorescence spectroscopy. The formation of nano-aggregates was confirmed by TEM and DLS. Additionally, 1H-NMR and FT-IR experiments show the Hg2+-binding mechanism and the evidence for the triazole-based amphiphile-Hg2+ complexes. The metal-amphiphile conjugates provide a useful and simple strategy for the detection of toxic heavy metal ions in aqueous medium.
