Tunablearylalkylionicliquids (TAAILs) based on the imidazolium cation were first reported in 2009. Since then, a series of TAAILs with different properties due to the electron-donating or -withdrawing effect of the substituents at the aryl ring has been developed. Herein, a wide variety of those ionicliquids (ILs) is presented in terms of their cation structure. The authors synthesized ILs containing
2009 年首次报道了基于咪唑鎓阳离子的可调谐芳烷基离子液体 (TAAIL)。此后,由于芳环上取代基的给电子或吸电子作用,开发了一系列具有不同性质的 TAAIL。在本文中,根据它们的阳离子结构呈现了多种这些离子液体 (IL)。作者合成了含有溴化物或双(三氟甲烷)磺酰亚胺阴离子和 1-芳基-3-烷基咪唑鎓阳离子的离子液体,在苯环的邻位和/或对位具有各种取代基以及不同长度的烷基链,从丁基到十二烷基不等. 根据它们的结构报告了这些 IL 的物理性质(熔点、热分解、粘度、电化学窗口)的差异。
