在本工作中，合成并表征了一系列新型的疏水性室温离子液体(ILS)。该离子液体由五个含双{(三氟甲基)磺酰亚胺、[NTF_2]−阴离子的醚官能化的硫阳离子组成。测定了它们的密度、粘度、离子电导率、电化学窗口等物理化学性质，以及相变行为和分解温度等热学性质。所有这些离子液体都表现出液体温度范围大、粘度低、导电性好的特点。此外，通过结合DFT计算和电化学表征，这些新型离子液体具有良好的电化学稳定性窗口，适合作为电解液材料在电化学储能装置中的潜在应用。
During this work, a novel series of 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, have been measured. All of these ILs showed large liquid range temperature, low viscosity, and good conductivity. Additionally, by combining DFT calculations along with electrochemical characterization it appears that these novel ILs show good electrochemical stability windows, suitable for the potential application as electrolyte materials in electrochemical energy storage devices.
