Abstract
The invention concerns ionic compounds in which the anionic load has been delocalized. A compound disclosed by the invention is comprised of an amide or one of its salts, including an anionic portion combined with at least one cationic portion M.sup.+m in sufficient numbers to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO.sup.+, an ammonium --NH.sub.4 +, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic portion matches the formula R.sub.F --SO.sub.x --N.sup.- Z, wherein R.sub.F is a perfluorinated group, x is 1 or 2, and Z is an electroattractive substituent. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.
