  • Patent number: 6171522
    Abstract: The invention relates to ionic compounds in which the anionic load has been displaced, and the uses of these compounds. A compound disclosed by the invention comprises an anionic portion combined with at least one cationic portion M+m in sufficient numbers to ensure overall electronic neutrality. The anionic portion is comprised of one of the groups (A) and (B): wherein Y1, Y2, Y3, Y4 and Y5 represent a carbonyl group, a sulfonyl group, a thiocarbonyl group, a thionyl group, a —C(═NCN)— or a —C(═C(CN)2)— group; Z represents an electroattractive radical; each of the substituents, RA, RB, RC and RD represents independently of one another a monovalent or divalent organic radical or is part of a polymer chain, with at least one of the substituents RC and RD being a perfluorinated radical. The compounds can be used especially for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.
