The invention concerns ionic compositions with high ionic conductivity, comprising a salt with delocalized anionic charge. An ionic composition comprises a salt dissolved in a solvent and has a conductivity higher than 10?-5¿ S.cm?-1¿ between -30 ·C and 150 ·C. The cation is a proton, a hydronium, a hydroxonium, a nitrosonium NO?+¿, an ammonium -NH¿4??+¿, or an organic or organometallic metal cation. The anion is a carbanion bearing a perfluorinated substituent or a substituent bearing at least a F on the .alpha. carbon of the carbanion, and two non-perfluorinated electroattractive substituents. Said composition can be used as electrolyte in electrochemical devices, as catalyst for chemical reactions, as photochemical or thermochemical initiator for polymerisation or cross-linking reactions.
L'invention concerne des compositions ioniques ayant une conductivité ionique élevée, comprenant un sel à charge anionique délocalisée. Une composition ionique comprend un sel en solution dans un solvant et a une conductivité supérieure à 10-5 S.cm-1 entre -30 ~C et 150 ~C. Le cation est un proton, un hydronium, un hydroxonium, un nitrosonium NO+, un ammonium -NH4+, ou un cation métallique, organique ou organo-métallique. L'anion est un carbanion portant un substituant perfluoré ou un substituant portant au moins un F sur le carbone en .alpha. du carbanion, et deux substituants électroattracteurs non perfluorés. Utilisation comme éléctrolyte dans les dispositifs électrochimiques, comme catalyseur de réactions chimiques, comme initiateur photochimique ou thermochimique pour des réactions de polymérisation ou de réticulation.
