hydrophobic room temperature ionic liquids (ILs) based on five ether functionalized sulfonium cations bearing the bis(trifluoromethyl)sulfonyl}imide, [NTf2]− anion were synthesized and characterized. Their physicochemical properties, such as density, viscosity and ionic conductivity, electrochemical window, along with thermal properties including phase transition behavior and decomposition temperature
在这项工作中,合成并表征了一系列基于带有双(三氟甲基)磺酰基}亚胺、[NTf 2 ] -阴离子的五种醚官能化锍阳离子的新型疏水性室温离子液体(IL)。测量了它们的物理化学性质,如密度、粘度和离子电导率、电化学窗口,以及热性质,包括相变行为和分解温度。所有这些离子液体都表现出大的液体温度范围、低粘度和良好的导电性。此外,通过将 DFT 计算与电化学表征相结合,这些新型离子液体显示出良好的电化学稳定性窗口,适合作为电化学储能装置中电解质材料的潜在应用。
