There are complex, scientific relationships between volume properties (molar volume, refractive index) and solvatochromic polarizability parameters (SP) of ionic liquids that were unpredictable. The interpretation of the correlations requires additional measurements to determine the dipolarity (SdP) of ionic liquids. Therefore, SdP values for the ionic liquids are to be determined with the aid of new 2-phenyl-substituted imidazole and imidazolium derivatives as dipolar fluorescence probes. An important point is the verification or independent determination of SdP values of ionic liquids via two-parameter equation relationships according to the Kamlet-Taft parameters. The preparation of new boronate-substituted dyes for determining the polarizability (SP) of ionic liquids is also planned.

离子液体的体积性质(摩尔体积、折射率)和溶致变色极化参数(SP)之间存在着复杂的科学关系，这些关系是不可预测的。对关联的解释需要额外的测量来确定离子液体的偶极(SDP)。因此，离子液体的SDP值将借助于新的2-苯基取代咪唑和咪唑衍生物作为偶极荧光探针来测定。重点是根据Kamlet-Taft参数，通过两参数方程关系验证或独立确定离子液体的SDP值。还计划制备用于测定离子液体极化率(SP)的新型硼酸盐取代染料。
