“…As is known, the coppercatalyzed azide-alkyne cycloaddition (CuAAC) is a broadly applicable and easy-to-handle reaction in the arsenal of organic chemistry [17,18]. Based on our previous experi-ence, perfluorinated/semifluorinated groups are constantly employed in designing multifunctional materials for enhancing self-assembly, such as bilayer formations in high diluted conditions [19][20][21][22][23]. Herein, we report the semifluoroalkyl triazole derivatives synthesized by CuAAC reaction (Scheme 1) as potential gelators or even PSGs.…”

Semifluoroalkyl triazole derivatives have been facilely synthesized by copper-catalyzed alkyne-azide cycloaddition reaction, which can gelate some organic solvents at weight concentrations of down to 0.5 wt.%. The gelation abilities of triazole derivatives with/without a semifluoroalkyl and an aromatic group were fully characterized. We found that triazole derivatives containing semifluoroalkyl chains and aromatic groups are typically effective in forming supramolecular organogels. Moreover, the gelator in ethyl acetate can solidify oil from an oil-water biphasic mixture for about 1 min.
