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 ¹H and ¹³C 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 (T_g = −62 °C) and high thermal stability (T_d10 = 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_DC = 7 × 10^–5 S cm^–1 at 30 °C).

1,2,3-三唑基聚（硅氧烷离子液体）均聚物的增强离子电导率

1,2,3-三唑基聚（硅氧烷离子液体）（PSIL）是通过聚[（巯丙基）甲基硅氧烷]和特制的乙烯基官能化三甘醇基之间的紫外触发硫醇-烯连接合成的。 1,2,3-三唑离子液体。硫醇-烯偶联的定量性质由¹ H 和¹³ C NMR 证明，而这种新 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光谱测量进行讨论。除了表现出低玻璃化转变温度 ( T _g = -62 °C) 和高热稳定性 ( T _d10= 284 °C)，这种新型聚 (1,2,3-三唑) 展示了迄今为止报道的 PIL 的体无水离子电导率最高值 (σ _DC = 7 × 10 ^–5 S cm ^–1 at 30 ° C）。
