Liquid Crystals and Ionic Liquids as Solvents

Liquid-crystalline media are important especially for technical and biomedical applications of electron-transfer reactions. Molecular electronic systems, photosynthetic processes, and some 

The one-electron oxidation of aromatic snbstrates can be facilitated in the alkylimidazolinm salt solutions by significant stabilization at the expense of n-n solnte-solvent interaction (Brooks and Doherty 2005). Polarity of ionic liqnids is also a favoring factor, bnt this polarity is close to that of normal polar organic solvents. According to estimations, ionic liqnids are more polar than acetonitrile and less polar than methanol (Reichardt 2005, 2007). 

One more difference between ionic liqnids and conventional organic solvents of the C-Cl cleavage should be mentioned. Normally, the intrinsic solvation of the developing halide ion disfavors the cleavage via the entropy term. Such a term cannot be significant in the ionic liquids composed of very bulky cations and anions.
