  • Patent number: 9932316
    Abstract: Novel imidazolium salts of formula (I) are described in which R is a C1-C14 alkyl group, optionally substituted by one or more fluorine atoms, or a C2-C18 alkoxyalkyl group, R? is an alkyl group containing at least 8 carbon atoms, at least 6 of which are partially or entirely fluorinated, R? is hydrogen or C1-C3 alkyl, 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.

  • Patent number: 9929343
    Abstract: The present invention relates to the doping of organic semiconductors and processes for producing layers of p-doped organic semiconductors. Disclosed is a process for p-doping organic semiconductors comprising treating the organic semiconductor with an oxidized salt of the organic semiconductor. A process for producing a layer of a p-doped organic semiconductor comprising producing a p-doped organic semiconductor by treating the organic semiconductor with an oxidized salt of the organic semiconductor; disposing a composition comprising a solvent and the p-doped organic semiconductor on a substrate; and removing the solvent is also described. Also disclosed is a process for producing a layer of a p-doped organic semiconductor comprising: disposing a composition comprising a solvent, the organic semiconductor and a protic ionic liquid on a substrate; and removing the solvent.
