  Low viscous and highly conductive phosphonium ionic liquids based on bis(fluorosulfonyl)amide anion as potential electrolytes

  摘要：

  The physical and electrochemical properties of room-temperature ionic liquids based on quaternary phosphonium cations together with a bis(fluorosulfonyl)amide anion are presented in this report. The bis (fluorosulfonyl)amide-based phosphonium ionic liquids were relatively low-melting, low viscous and highly conductive when compared to those of the corresponding bis(trifluoromethylsulfonyl)amide-based ionic liquids. Particularly, the ionic liquids containing a methoxy group in the phosphonium cations indicated very low viscosities and high conductivities. The FSA-based phosphonium RTILs were thermally stable up to nearly 300 degrees C. The voltammetric analysis suggested that the bis(fluorosulfonyl)amide-based phosphonium ionic liquids showed high electrochemical stability similar to the corresponding bis(trifluoromethylsulfonyl) amide-based ionic liquids.

  基于季phospho阳离子的室温双氰胺离子液体的物理和电化学性质

  摘要：

  本报告介绍了基于季phospho阳离子和双氰胺阴离子的室温离子液体的物理化学和电化学性质。所制备的大多数基于双氰胺的phospho离子液体是亲水的，除了在膦鎓阳离子中包含长烷基链的离子液体。发现不对称的nium阳离子与双氰胺阴离子结合产生低熔点的盐。与相应的铵离子液体相比，基于双氰胺的phospho离子液体表现出相对较低的粘度和较高的电导率。特别地，在phospho阳离子中含有甲氧基的离子液体显示出非常低的粘度。通过伏安法测量证实了基于双氰胺的phospho离子液体的相对较好的电化学稳定性。热重分析表明，基于双氰胺的phospho离子液体显示出比相应的铵离子液体更高的热稳定性，表明the阳离子对热稳定性的改善作用。

  A series of room-temperature ionic liquids (ILs) composed of triethyl(alkyl)phosphonium cations paired with three different aprotic heterocyclic anions (AHAs) (alkyl = butyl ([P2224]+) and octyl ([P2228]+)) were prepared to investigate the effect of cationic alkyl chain length on transport properties. The transport properties and density of these ILs were measured from 283.15 K to 343.15 K at ambient

• Effect of Cation on Physical Properties and CO₂ Solubility for Phosphonium-Based Ionic Liquids with 2-Cyanopyrrolide Anions

  A series of tetraalkylphosphonium 2-cyanopyrrolide ([P-nnnn][2-CNPyr]) ionic liquids (ILs) were prepared to investigate the effect of cation size on physical properties and CO2 solubility. Each IL was synthesized in our laboratory and characterized by NMR spectroscopy. Their physical properties, including density, viscosity, and ionic conductivity, were determined as a function of temperature and fit to empirical equations. The density gradually increased with decreasing cation size, while the viscosity decreased noticeably. In addition, the [P-nnnn] [2-CNPyr] ILs with large cations exhibited relatively low degrees of ionicity based on analysis of the Walden plots. This implies the presence of extensive ion pairing or formation of aggregates resulting from van der Waals interactions between the long hydrocarbon substituents. The CO2 solubility in each IL was measured at 22 degrees C using a volumetric method. While the anion is typically known to be predominantly responsible for the CO2 capture reaction, the [P-nnnn][2-CNPyr] ILs with shorter alkyl chains on the cations exhibited slightly stronger CO2 binding ability than the ILs with longer alkyl chains. We attribute this to the difference in entropy of reaction, as well as the variation in the relative degree of ionicity.
