  作为离子液体微环境探针的咪唑阳离子在C2位置的CD振动。

  摘要：

  与分子溶剂不同，基于咪唑鎓的离子液体完全由具有空间异质性的离子制成。需要能够评估这些复杂液体的阳离子附近的微环境的光谱探针。在本手稿中，我们描述了使用CD振动探针标记咪唑阳离子的C2位置的简单化学程序，并通过线性和非线性振动光谱表明，这种CD拉伸模式可以用作评估溶剂微环境和溶剂的有用分析工具。从阳离子的角度看，咪唑基离子液体中的溶质-溶剂相互作用。可以预期，这种CD振动阳离子探针将导致开发创新的实验策略，从而可以更好地理解此类离子液体。

  New hydrophobic ionic liquids with perfluoroalkyl phosphate and cyanofluoroborate anions

  摘要：

  Novel hydrophobic ionic liquids (ILs) with tris(perfluoroalkyl)trifluorophosphate anions (e.g. [(C2F5)(3)PF3](-); FAP anion), the bis[bis(pentafluoroethyl)phosphinyl]imide (FPI) anion, the tetracyanoborate (TCB) anion, the tricyanofluoroborate (MFB) anion and the dicyanodifluoroborate (DDB) anion have been developed. The properties of these ionic liquids, i.e. their thermal and electrochemical stabilities as well as their viscosities, densities and refractive indices were studied and will be discussed. FAP ionic liquids are more hydrolytically stable and less viscous compared to ionic liquids with the hexafluorophosphate ([PF6](-)) anion. The hydrophobicity of ionic liquids with the cyano- and fluoroborate anions [BFx(CN)(4-x)](-) (x = 0-4) strongly decrease in the order: EMIM[B(CN)(4)] > EMIM[BF(CN)(3)] > EMIM[BF2(CN)(2)] > EMIM[BF3(CN)] similar to EMIM[BF4]; EMIM[BF3(CN)] as well as EMIM[BF4] are miscible with water. The lowest viscosity for all ionic liquids composed of the EMIM cation and weakly coordinating anions as the ones presented herein was observed for EMIM[BF2(CN)(2)] (11.1 mPa.s at 20 degrees C).

  PHIP NMR Spectroscopy in Ionic Liquids: Influence of Salts on the Intensity of Polarization Signals

  摘要：

  离子液体中的对氢诱导动态核极化 NMR 光谱（PHIP）会导致极化信号微弱或无极化信号，具体取决于实验类型。我们证明，极化强度与离子液体的浓度直接相关。高离子浓度与快速 T1 弛豫有关，导致极化信号湮灭。

  stable passivation layer that prevents Al corrosion, the Al electrode in the Na[FSA]-[C2C1im][FSA] ([FSA] = bis(fluorosulfonyl)amide and [C2C1im] = 1-ethyl-3-methylimidazolium) IL, is found to be afflicted by pitting corrosion at potentials above 4 V vs Na+/Na during electrochemical measurement at 90 °C. Therefore, this study investigates the suppressive effect of [FAP]− (FAP = tris(pentafluoroethyl)trifluorophosphate)

  基于磺酰胺型阴离子的离子液体 (IL) 作为二次电池的电解质已获得广泛应用。虽然已知基于磺酰胺的 IL 电解质可形成稳定的钝化层以防止铝腐蚀，但 Na[FSA]-[C 2 C 1 im][FSA]（[FSA] = 双（氟磺酰基）酰胺和[C 2 C 1 im] = 1-ethyl-3-methylimidazolium) IL，被发现在 90 °C 的电化学测量期间，在高于 4 V vs Na + /Na的电位下受到点腐蚀的影响。因此，本研究调查了 [FAP] 的抑制作用-（FAP = 三（五氟乙基）三氟磷酸盐）对 IL 电解质的铝腐蚀行为。在这里，通过一系列循环伏安法测量、扫描电子显微镜和能量色散 X 射线光谱证实了铝电极的腐蚀得到抑制。使用 Na 3 V 2 (PO 4 ) 2 F 3正电极进行的充放电测试表明，将 [FAP]添加到IL 中可提高 90 °C 中间温度下的循环性能。
