Micellar and vesicular nanoassemblies of triazole-based amphiphilic probes triggered by mercury(ii) ions in a 100% aqueous mediumElectronic supplementary information (ESI) available: Detailed synthetic and experimental procedures. See DOI: 10.1039/c4cc06742h

ABA-type amphiphiles bearing a triazole-based aromatic block were easily synthesized using click chemistry, which act as fluorescent turn-off Hg 2+ -chemoprobes in an aqueous solution. Interestingly, the metal-binding process of amphiphiles induced nanoassemblies even below the CMCs, and the binding stoichiometry affected the morphologies of the resultant nanostructures. Selective Hg 2+ -binding of click-derived triazole-based amphiphiles can lead to the formation of nanostructures, even below CMCs, which are determined by the stoichiometry of amphiphile-Hg 2+ complexes affecting the interfacial curvature.
