Herein we report the synthesis of a series of
poly(4-alkyl-1-vinyl-1,2,4-triazolium) poly(ionic liquid)s either via
straightforward free radical polymerization of their corresponding ionic liquid
monomers, or via anion metathesis of the polymer precursors bearing halide as
counter anion. The ionic liquid monomers were first prepared via N-alkylation
reaction of commercially available 1-vinyl-1,2,4-triazole with alkyl iodides,
followed by anion metathesis with targeted fluorinated anions. The thermal
properties and solubilities of these poly(ionic liquid)s have been
systematically investigated. Interestingly, it was found that the
poly(4-ethyl-1-vinyl-1,2,4-triazolium) poly(ionic liquid) exhibited an improved
loading capacity of transition metal ions in comparison with its imidazolium
counterpart.Comment: 18 pages, 9 figure
