The invention relates to a process for the preparation of salts having perfluoroalkyltricyano- or perfluoroalkylcyanofluoroborate anions, ((per)fluoro)phenyltricyano- or ((per)fluoro)phenylcyanofluoroborate anions, phenyltricyanoborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms or phenylcyanofluoroborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms, by reaction of alkali metal trifluoroperfluoroalkylborate with trialkylsilyl cyanide and a subsequent salt-exchange reaction or by direct reaction of an organic trifluoroperfluoroalkyl borate with trialkylsilyl cyanide.

Process for the preparation of perfluoroalkylcyano- or perfluoroalkylcyanofluoroborates

The invention relates to new compounds containing alkyl/alkenyl-cyano-borate or alkyl/alkenyl-cyano-fluoroborate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Compounds containing alkyl-cyano-borate or alkyl-cyano-fluoroborate anions

The invention relates to a process for the preparation of salts having perfluoroalkyltricyano- or perfluoroalkylcyanofluoroborate anions, ((per)fluoro)phenyltricyano- or ((per)fluoro)phenylcyanofluoroborate anions, phenyltricyanoborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4C atoms or phenylcyanofluoroborate anions which are mono- or disubstituted by perfluoroalkyl groups having 1 to 4C atoms, by reaction of alkali metal trifluoroperfluoroalkylborate with trialkylsilyl cyanide and a subsequent salt-exchange reaction or by direct reaction of an organic trifluoroperfluoroalkyl borate with trialkylsilyl cyanide.

The invention relates to new compounds containing alkyl-alkoxy-cyano-borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Compounds containing alkyl-alkoxy-cyano-borate anions

The present invention relates to electrolyte formulations comprising at least one compound of formula (I) M[B(R)(CN)(F)]&#x2014; (I) in which Ma+ is an inorganic or organic cation, Rdenotes straight-chain or branched perfluoroalkyl groups having 1 to 4 C atoms, CF, CH, partially fluorinated phenyl or phenyl which is monosubstituted or disubstituted by perfluoroalkyl groups having 1 to 4 C atoms, a is 1 or 2, x is 1, 2 or 3, y is 0, 1 or 2 and x+y is 3 and their use in an electrochemical and/or optoelectronic device such as a photovoltaic cell, a capacitor, a light emitting device, an electrochromic or photo-electrochromic device, an electrochemical sensor and/or biosensor, preferably their use in a dye or quantum dot sensitized solar cell.
