The glassy, supercooled, and normal liquid states of the 1-alkyl-3-methylimidazolium tricyanomethanide series [CnC1im][TCM] (n = 2, 4, 6, 8, and 16) were investigated by dielectric and mechanical (rheological) experiments supplemented by X-ray diffraction. The conductivity relaxation was found to be accompanied by a pronounced secondary relaxation. However, based on ambient and high-pressure results as well as the coupling model, we assumed that the latter one can not be classified as Johari-Goldstein relaxation. Moreover, the studies on the nanoscale organization of ionic liquids indicated that 1-alkyl-3-methylimidazolium tricyanomethanide ILs begin to form nanoscale aggregates when the alkyl chain of the cation has six carbon atoms.
通过介电和力学（流变学）实验并辅以X射线衍射，研究了1-烷基-3-甲基咪唑鎓三氰甲烷化物系列[CnC1im][TCM]（n = 2、4、6、8和16）的玻璃态、过冷态和正常液态。发现电导率弛豫伴随着明显的次级弛豫。然而，基于常压和高压结果以及耦合模型，我们认为后者不能归类为乔哈里-戈尔茨坦弛豫。此外，对离子液体纳米级组织的研究表明，当阳离子的烷基链含有六个碳原子时，1-烷基-3-甲基咪唑鎓三氰甲烷化物离子液体开始形成纳米级聚集体。
