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

A modified carbonaceous material having chemically bound on its surface at least one fluoropolyoxyalkylene chain (chain R) and a process for the modification of a carbonaceous material [material (C)]. The process comprises: contacting the material (C) with a (per)fluoropolyether peroxide comprising at least one peroxidic moiety comprised between spcarbon atoms and at least one fluoropolyoxyalkene chain (chain R), i.e. a fluorocarbon segment comprising ether linkages in main chain [peroxide (P)]; and heating the material (C) while in contact with the peroxide (P) at a temperature exceeding decomposition temperature of the peroxide (P).
