The persistent achievements of ionic liquids in various fields, including medicine and energy necessitate the efficient development of novel functional ionic liquids that exhibit favorable characteristics, alongside the development of practical and scalable synthetic methodologies. Ionic liquids are fundamentally understood as materials in which structure begets function, and the function and applicability of ILs is of utmost concern. It was recently reported that "full fluorosulfonyl" electrolyte is compatible with both the Li metal anode and the metal-oxide cathode that is crucial for the development of high-voltage rechargeable lithium-metal batteries. Inspired by these results, for the first time, we reported the synthesis of a series of ionic liquids with a sulfonyl fluoride motif using an highly effective and modular fluorosulfonylethylation procedure. Herein, we present a detailed analysis of novel sulfonyl fluoride-based ionic liquids paired with the hexafluorophosphate anion. We employed a combination of computational modeling and X-ray crystallographic studies to gain an in-depth understanding of their structure-property correlations.
离子液体在包括医学和能源在内的各个领域所取得的持续成就，使得开发具有良好特性的新型功能性离子液体以及实用且可扩展的合成方法变得十分必要。从根本上讲，离子液体被理解为结构决定功能的材料，离子液体的功能和适用性备受关注。最近有报道称，“全氟磺酰基”电解质与锂金属阳极和金属氧化物阴极均兼容，这对于高压可充电锂金属电池的开发至关重要。受这些结果的启发，我们首次报道了使用高效且模块化的氟磺酰乙基化方法合成了一系列具有磺酰氟基团的离子液体。在此，我们对与六氟磷酸根阴离子配对的新型磺酰氟基离子液体进行了详细分析。我们采用了计算建模和X射线晶体学研究相结合的方法，以深入了解它们的结构-性质关系。
