Novel imidazolium salts of formula (I) are described in which R is a C-Calkyl group, optionally substituted by one or more fluorine atoms, or a C-Calkoxyalkyl group, R' is an alkyl group containing at least 8 carbon atoms, at least 6 of which are partially or entirely fluorinated, R&#x2033; is hydrogen or C-Calkyl, Z is an organic or inorganic anion, and Q is further defined. The compounds of formula (I) are liquid crystals over a wide temperature range, and are characterized by high conductivity, hydrophobicity and stability. These properties made them ideally suitable for use in devices based on electrochemical reactions, such as solar cells, fuel cells, electrochemical sensors, lithium batteries and capacitors, etc. 

Imidazolium salts having liquid crystal characteristics, useful as electrolytes

The present invention relates to a process for the preparation of materials with nanometric dimensions and controlled shape, based on titanium dioxide. The invention also relates to a process for the preparation of titanium dioxide nanorods and nanocubes with anatase phase composition, which are highly suitable for photocatalytic use, in particular for applications involving photovoltaic cells, for example Dye Sensitized Solar Cells (DSSC), photoelectrolysis cells and tandem cells for the conversion of solar energy and the production of hydrogen.
