| 中文摘要: |
| 通过一步法合成了基于1,3-二烷基咪唑阳离子和甲烷磺酸或对甲苯磺酸阴离子的无卤素离子液体，并对它们的物理化学性质如聚集行为、表面性质、热性质、密度、黏度、折光率、摩擦学性能和电化学性质等进行了详细研究。结果表明在甲烷磺酸阴离子基离子液体中观察到离子液体中普遍存在的离子簇行为；同等条件下[BEim]MS的荧光光谱强度较[BEim]TS弱；[C12Mim]MS展现出液晶行为；[TS]-基离子液体有着较高的折光率，大于1.51。 |
| 英文摘要: |
| Ten halogen-free ionic liquids (ILs) based on 1,3-dialkylimidazolium cations and methanesulfonate [MS]- or p-toluenesulfonate [TS]- anions were synthesized via one-step reaction, and their physicochemical properties such as aggregation behavior, surface property, thermal property, density, viscosity, refractive index and electrochemical properties have comparatively been studied. The results showed that ion cluster behavior was observed for the methanesulfonate anion ILs. The emission spectra of neat [BEim]MS only gave relatively weak fluorescence, whereas [BEim]TS exhibited strong emission behavior under same conditions. Ten studied ILs displayed five different phase behaviors, of which [C12Mim]MS exhibited a liquid crystal behavior. The [TS]- based ILs showed high refractive indices of > 1.51. |
