SPP 1191:  Ionic Liquids

• Subject Area: Chemistry ; Physics ; Thermal Engineering/Process Engineering
• Term: from 2006 to 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 12918457

The Priority Programme is dedicated to improving understanding of the special nature of ionic liquids through fundamental research. Therefore, the main goal of the programme is the detailed investigation of the interactions between the components of an ionic liquid (ions and ion clusters), on the one hand, and of the nature of interactions between ionic liquids and dissolved substances or between ionic liquids and interphases, on the other. We hope that this research effort will lead to experimentally validated models that will enable the structural optimisation of ionic liquids to achieve given or desired property profiles. Such models are considered to be the key to accelerating future development in ionic liquid research. The following three central research fields have been defined.
(1) Order, dynamics and structure of ionic liquids:
In the past very few systematic studies have been carried out to elucidate the order, dynamics and structure of ionic liquids. However, in these few investigations interesting and unusual phenomena have been observed which should be explained, understood and further developed. Examples of such phenomena are ion cluster formation and the liquid crystalline behaviour of some ionic liquids. The contributions of different influences (Coulombic interaction, hydrogen-bonding, van-der-Waals forces) to these effects have to be understood and will have to be discussed in the light of specific chemical structures of cation/anion combinations.
(2) Interaction of ionic liquids with dissolved substances and interphase interactions:In this part of the programme the specific solvation properties of ionic liquids and their interphase interactions are under investigation. Examples of probes for the solvation experiments include molecular compounds of different polarity, dissolved ions, electrons, metal complexes or transition states of reactions. Examples of interphase-ionic liquid interactions include interactions with surfaces of metals, with organic or inorganic solids as well as with the surfaces of poorly miscible or immiscible fluids.
(3) New structures forming ionic liquids:This field of the programme aims to expand the known range of structures that form ionic liquids. Examples of this field include new, highly functionalised or chiral ionic liquids.
