A 1,2,3-triazolium-based poly(siloxane ionic liquid) (PSIL) is synthesized by UV-triggered thiol-ene ligation between a poly[(mercaptopropyl)methylsiloxane] and a tailor-made vinyl-functionalized triethylene glycol-based 1,2,3-triazolium ionic liquid. The quantitative nature of the thiol-ene coupling is demonstrated by H and C NMR, whereas properties of this new PSIL are discussed based on solubility, size exclusion chromatography, differential scanning calorimetry, thermogravimetric analysis, and broadband dielectric spectroscopy measurements. Besides exhibiting low glass transition temperature ( = -62 °C) and high thermal stability ( = 284 °C), this new class of poly(1,2,3-triazolium) demonstrates the highest value of bulk anhydrous ionic conductivity reported to date for PILs (σ = 7 × 10 S cm at 30 °C).
通过聚[（巯基丙基）甲基硅氧烷]与特制的乙烯基官能化三甘醇基1,2,3 - 三唑鎓离子液体之间的紫外光引发硫醇 - 烯连接反应，合成了一种基于1,2,3 - 三唑鎓的聚（硅氧烷离子液体）（PSIL）。硫醇 - 烯偶联反应的定量性质通过氢核磁共振（H NMR）和碳核磁共振（C NMR）得以证明，而这种新型PSIL的性质则基于溶解度、尺寸排阻色谱、差示扫描量热法、热重分析和宽带介电谱测量进行了讨论。除了具有低玻璃化转变温度（Tg = -62 °C）和高热稳定性（Td = 284 °C）外，这类新型聚（1,2,3 - 三唑鎓）还展现出了迄今为止报道的离子液体中最高的本体无水离子电导率值（30 °C时σ = 7 × 10⁻⁵ S cm⁻¹）。
