The current application represents a continuation of our previous SNF project with the same title, concerned with the study of ionic liquids (ILs) at a fundamental level, but with certain applications in mind. The synthesis and application of ILs have enjoyed explosive growth in the past 10-15 years. Scientists from many different research areas have contributed to making the field of IL research highly multidisciplinary and truly exciting. Despite the on-going research efforts in ILs chemistry there are many interesting areas that have received surprisingly little attention. One obvious feature from an analysis of the domain is that the majority of the fundamental research deals with structural variations to the cation, based on a limited number of anions, notably tetrafluoroborate (BF4-), hexafluorophosphate (PF6-) and bis(trifluoromethylsulfonyl)imide (Tf2N-), which are all rich in fluorine - albeit with some exceptions. In other words, the chemistry of ILs could be defined as cation chemistry. Now that IL cations have been extensively studied, it is perhaps time to emphasize and focus new attention on IL anions. For example, the majority of studies employing ILs are composed of imidazolium, ammonium, pyridinium cations with fluorous anions. Non-fluorous ILs based on systems containing tricyanomethanide (TCM) and tetracaynoborate (TCB) anions have lower than expected melting points and viscosities, nevertheless, they remain largely unexplored. Compared to the commonly used ILs composed of singly charged cations and anions, multi-charged ILs such as dicationic systems and dianionic systems, have also received only limited attention. In this project we intend to open three new research themes that are outlined below: 1. We intend to prepare new ILs with tricyanomethanide (TCM) and tetracaynoborate (TCB) anions with potentially useful physical properties. Due to the limited availability of these salts, fundamental investigations and applications of ILs derived from them remain largely unexplored. We intend to prepare a series of TCM- and TCB-based ILs and study the relationship between their structures and their physical properties. As the CN groups of the anion can potentially coordinate to metal centres we will also examine the coordinating ability of the anion, and the synthesis of the so-called soft-materials, with the anions acting as multidentate ligands to coordinate to metal ions. In addition, these ILs will be evaluated in super capacitors in collaboration with Dr. Rüdiger at the Paul Scherrer Institute (PSI). 2. Imidazolium polyiodides will be studied also with a focus on relationship of structural aspects and physical properties. Possible interactions such as I-I···I-, I-I···H-X and I-I···p interactions will be analysed. One of the important applications of imidazolium polyiodide salts is as electrolytes in dye-sensitized solar-cells. Consequently, the relationship between conductivity and structure of the polyiodide salts will be studied. In addition, these ILs will be evaluated in dye-sensitized solar cells in collaboration with Prof. Grätzel at the EPFL.3. New dicationic and dianionic imidazolium salts will be developed and the relationship between the structure and the physical properties will be explored. As far as we are aware no ILs containing dianions have been reported and it is likely that considerable efforts will be required to obtain low melting systems. Notably, some applications of the new ILs, e.g. as nanoparticle stabilizers and as reaction media in various types of reactions will be explored.As the only group developing new ILs in Switzerland we have numerous interactions with other Swiss research groups wanting to collaborate with us. As mentioned above, Dr. Rüdiger at the PSI on super capacitors and Prof. Grätzel at the EPFL on solar cells, and also Prof. Shea at EPFL (Neuchatel Campus) and Prof. Ivo Utke at Swiss Federal Laboratories for Materials Science and Technology (EMPA) on ion sources. To fully support all the these projects we request increasing the number of personnel working on this project from two to three PhD students.
