• Ionic liquid-gas interfaces: more than a surface glance
• 更新时间：2014-12-30；信息类型：国外研究进展
• Research by scientists in the UK suggests that small changes in the nature of binary ionic liquid systems can significantly alter their surface composition. The findings may aid the design of ionic liquid films for applications such as gas capture and supported catalysis, where surface adsorption is essential.

• Investigation of cation–anion interaction in 1-(2-hydroxyethyl)-3-methylimidazolium-based ion pairs by density functional theory calculations and experiments
• 更新时间：2014-04-10；信息类型：SCI论文
• Gas-phase structure, hydrogen bonding, and cation–anion interactions of a series of 1-(2-hydroxyethyl)-3- methylimidazolium ([HOEMIm]+)-based ionic liquids (hereafter called hydroxyl ILs) with different anions (X=[NTf2]–, [PF6]–, [ClO4]–, [BF4]–, [DCA]–, [NO3]–, [AC]– and [Cl]–), as well as 1-ethyl-3-methylimizolium ([EMIm]+)-based ionic liquids (hereafter called nonhydroxyl ILs), were investigated by density functional theory calculations and experiments. Electrostatic potential surfaces and optimized structures of isolated ions, and ion pairs of all ILs have been obtained through calculations at the Becke, three-parameter, Lee–Yang–Parr/6-31+G(d,p) level and their hydrogen bonding behavior was further studied by the polarity and Kamlet–Taft Parameters, and 1H-NMR analysis. In [EMIm]+-based nonhydroxyl ILs, hydrogen bonding preferred to be formed between anions and C2–H on the imidazolium ring, while in [HOEMIm]+-based hydroxyl ILs, it was replaced by a much stronger one that preferably formed between anions and OH. The O–H___X hydrogen bonding is much more anion-dependent than the C2–H___X, and it is weakened when the anion is changed from [AC]– to [NTf2]–. The different interaction between [HOEMIm]+ and variable anion involving O–H___X hydrogen bonding resulted in significant effect on their bulk phase properties such as 1H-NMR shift, polarity and hydrogen-bond donor ability (acidity, a).
