Polyaniline as an indicator of the non-clustered water in ionic liquids — •Elena Tomšík, Elizaveta Alekseeva, and Natalia Gospodinova — Institute of Macromolecular Chemistry AS CR, Heyrovsky Sq. 2, 162 06 Prague 6, Czech Republic

Reversible red-shift of long-wavelength absorption accompanying adsorption of water by thin polycrystalline polyaniline films is considered to be a sign of superficial water-promoted formation of liquid crystalline phase. Moreover, this effect is favored by the presence of highly hydrated ions which destroy clustered water. Such simple optical test has been used by us to detect the presence of the non-clustered water in the ionic liquids. Correlation between structure of anions/cations composed ionic liquid and content of non-clustered water is revealed.
