"Mutual Lewis-Acid-Base Interactions of Cations and Anions in Ionic Liquids";
Chemistry - A European Journal, 19 (2013), 1; S. 288 - 293.



Kurzfassung englisch:
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.
