摘要

Hyperbranched poly(triazole) with tertiary amine moiety and longer flexible polyethylene glycol (PEG) terminal group (hb-PTA-PEG) was synthesized by successive Cu(I)-catalyzed azide-alkyne cycloaddition polymerization, and the corresponding hyperbranched poly(triazolium)s containing hybrid quaternary ammonium ion, [hb-PTA-PEG]⁺[I]⁻ and [hb-PTA-PEG]⁺[TFSI]⁻, were obtained after N-alkylation and anion exchange reactions. These hyperbranched polymers presented broad electrochemical stability window of above 6.0 V versus Ag⁺/Ag and 5.3 V versus Li⁺/Li, and displayed low glass transition temperature in the range of −13 to −37 °C, owing to the hyperbranched structure combined with the hybrid ionic moiety and longer flexible PEG end-group. The ionic [hb-PTA-PEG]⁺[TFSI]⁻ showed superior ionic conductivity, which was above 10⁻⁵ S cm⁻¹ at 30 °C.
