Abstract

original image

Step growth polymerization of an α-azide-ω-alkyne monomer by copper-catalyzed azide-alkyne cycloaddition affords a high molar mass linear poly(1,2,3-triazole) that is subsequently reacted with iodomethane to yield the corresponding poly(3-methyl-1,2,3-triazolium iodide) derivative. The formation of this new type of poly(ionic liquid) having main-chain 1,2,3-triazolium groups in the repeating unit is demonstrated by 1H NMR. The large variety of 1,2,3-triazole-based architectures accessible by anion exchange and macromolecular engineering through click chemistry open new perspectives in the field of poly(ionic liquid)s.
