Abstract A water-processable nanoreactors are increasingly investigated to develop the environment-friendly catalyst. Amphiphilic molecules can self-assemble into various nanostructures such as micelles, fibrils, vesicular structures and sheets, etc depending on the molecular design. Especially, supramolecular nanoreactors based on amphiphilic molecules are of great interest as a nanocatalysts with large quantity of catalytically active sites within the nano-architectures. Meanwhile, “click chemistry” has been widely used to prepare new functional materials by allowing to link together different molecular fragments with synthetic simplicity, mild reaction condition, fast and quantitative reaction. Interestingly, the resulting click-derived triazole group plays a role as a ligand for chelating metal ion with specific binding affinity depending on the triazole-containing molecular structure. In this work, triazole-based amphiphilic molecules containing aromatic and hydrophilic tri(ethylene oxide) segment were easily synthesized using facile click chemistry. The Cu2+-nanoassemblies can be a facile nanocatalyst for activating the azide-alkyne cycloaddition in aqueous medium by reduction of the Cu2+ to Cu+. The interesting point is that the metal-captured nanostructures can induce the molecular synthesis by click reaction in water and further, the click-derived products could control the morphology of nanoreactor depending on the molecular structure of products.
