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.sup.+m in sufficient numbers to ensure overall electronic neutrality. The anionic portion is comprised of one of the groups (A) and (B): ##STR1## wherein Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4 and Y.sub.5 represent a carbonyl group, a sulfonyl group, a thiocarbonyl group, a thionyl group, a --C(.dbd.NCN)-- or a --C(.dbd.C(CN).sub.2)-- group; Z represents an electroattractive radical; each of the substituents, R.sub.A, R.sub.B, R.sub.C and R.sub.D 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 R.sub.C and R.sub.D 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.
