Abstract
The invention relates to ionic compounds in which the negative charge is highly delocalized. The compounds comprise at least one perfluorovinyl group and at least one group chosen from --O or one of the groups --NC.ident.N, --C(C.ident.N).sub.2, --NSO.sub.2 R or --C[SO.sub.2 R].sub.2 or a pentacyclic group comprising at least one N, C--C.ident.N, CR, CCOR or CSO.sub.2 R group. The compounds and/or their polymers are of use in the preparation of ionically conducting materials, electrolytes and selective membranes.
