用溶剂变色探针高压光谱法研究了由咪唑阳离子和各种阴离子组成的室温离子液体的溶剂化性质。我们测量了Kamlet-Taft溶剂变色参数(π*，β)和微粘度(η)与压力的关系。结果表明，π*和β对咪唑阳离子和多原子阴离子类型不敏感，但对单原子阴离子类型敏感。微粘度与压力的关系符合经验的幂定律方程。
The solvation properties of some room-temperature ionic liquids consisting of imidazolium cations and various anions were examined by means of the high-pressure spectroscopy with solvatochromic probes. We measured the pressure dependence of Kamlet-Taft solvatochromic parameters (π*, β) and microviscosity (η). It was found that π* and β were not so sensitive to the types of imidazolium cations and polyatomic anions, but the type of monoatomic anions. The pressure dependence of microviscosity was found to obey the empirical power-law equation.
