摘要

用x射线光电子能谱分析了一系列咪唑基和吡啶基桥式离子液体。研究了这些指示物的不同电子环境，并建立了碳C1s区域的稳健拟合模型。测定了不同C1s组分和指示物N1s的相对位置，得到了芳香碳态和脂肪碳态的配合C1s光能光谱，光能峰在结合能289.0 ~ 283.9 eV之间。当代的拟合方法已应用于不同的一组环境，允许比较咪唑和吡啶基阳离子离子液体的阳离子组分的结合能。同时，还根据指示离子液体的XP谱计算了所有碳和氮的实验化学计量。

An X-ray photoelectron spectroscopy study of ionic liquids based on a bridged dicationic moiety

A series of imidazolium and pyridinium-based bridged dicationic ionic liquids have been analysed using X-ray photoelectron spectroscopy. The different electronic environments of the dications have been investigated and a robust fitting model for the carbon C1s region has also been developed. The relative positions of different C1s components and N1s of dications have been determined and their complex C1s photoemission spectra produced from both aromatic and aliphatic carbon states giving photoemission peaks in the binding energy range of 289.0–283.9 eV. A contemporary fitting approach has been applied to a different set of environments which allowing comparison of the binding energies of cationic components of imidazolium and pyridinium-based dicationic ionic liquids. The experimental stoichiometry of all the carbons and nitrogens have also been calculated from XP spectra of the dicationic ionic liquids.

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
