众所周知，由于溶剂化作用，溶质性质受到溶剂分子的强烈影响。这是由于溶质和溶剂的性质强烈依赖于彼此而导致的相互作用。本论文基于离子液体是阴离子溶剂化的阳离子和阳离子溶剂化的阴离子的想法。为了证明这种（在该系统中非常明显）相互作用，维克多·古特曼（Viktor Gutmann）长期以来建立的溶液中溶剂和离子的供体-受体概念被扩展到离子液体。许多溶剂参数，例如离子液体的 Kamlet-Abboud-Taft 和 Dimroth-Reichardt ET 标度忽略了这种相互影响，然而，这实际上对于正确描述离子液体性质来说是必要的。显示了当考虑反离子的影响时这些参数变化的强度。此外，还给出了离子液体的受体和供体数。
Solute properties are known to be strongly influenced by solvent molecules due to solvation. This is due to mutual interaction as both the properties of the solute and of the solvent strongly depend on each other. The present paper is based on the idea that ionic liquids are cations solvated by anions and anions solvated by cations. To show this (in this system strongly pronounced) interaction the long time established donor–acceptor concept for solvents and ions in solution by Viktor Gutmann is extended to ionic liquids. A number of solvent parameters, such as the Kamlet–Abboud–Taft and the Dimroth–Reichardt ET scale for ionic liquids neglect this mutual influence, which, however, seems to be in fact necessary to get a proper description of ionic liquid properties. It is shown how strong such parameters vary when the influence of the counter ion is taken into account. Furthermore, acceptor and donor numbers for ionic liquids are presented.
