| abstract |
The invention relates to ionic compounds in which the negative charge is highly relocated. The compounds contain at least one perfluorovinyl group and at least one chosen group among -O or one of the groups -NC.ident.N, -C (C.ident.N) 2, -NSO2R, -C [SO2R] 2 or a pentacyclic group comprising at least one N group, CC.ident.N, CR, CCOR or CSO2R. Compounds and / or their polymers are useful for the elaboration of conductive materials ionic, electrolytes and selective membranes. |
