A set of eight functional 4-vinyl-1,2,3-triazolium monomers were synthesized using copper catalyzed azide-alkyne 2 + 3 Huisgen cycloaddition. These vinyl-trizolium monomers readily polymerized via free radical polymerization. The physical properties of the vinyl-triazolium based poly(ionic liquid)s (PILs) are strongly dependent on the pendant functional groups. These polymers were characterized for glass transition temperature (T-g), solubility, and the thermal decomposition. The vinyl-triazolium based PILs offer an efficient route to highly functional PILs with the advantage of facile synthesis and the ability to incorporate many desirable functional moieties.
