Description:

Glycidyl triazolyl polymer (GTP)-based anionic poly(ionic liquid)s comprising the trifluoromethanesulfonimide (TFSI) anion pendant and the 1-ethyl-3-methylimidazolium (EMIM) countercation were synthesized through Cu(I)-catalyzed azide−alkyne cycloaddition between a glycidyl azide polymer and anionic alkyne derivatives. These polymers were designed as oppositely charged analogs of the cationic GTPs reported previously. The anionic GTPs were characterized by NMR, IR, size-exclusion chromatography, differential scanning calorimetry, thermogravimetric analysis, and impedance measurements. The anionic GTPs reported herein exhibited a lower critical solution temperature (LCST) type phase separation in acetone. The anionic GTPs with a longer side-chain spacer exhibited a lower glass transition temperature (Tg) and higher ionic conductivity (1.7 × 10−6 S cm−1 at 25 °C under anhydrous conditions).
