SULFONAMIDE MACROMOLECULES USEFUL AS SINGLE-ION CONDUCTING POLYMER ELECTROLYTE

摘要

The present invention relates to asymmetric sulfonamide compounds comprising at least: • one polycyclic group, Ar, formed of two to six rings, at least one of which is aromatic, • a linear or branched, saturated or unsaturated aliphatic chain, said chain possibly being interrupted by one or more heteroatoms, • said group Ar and said aliphatic chain being covalently bonded via a spacer represented by a sulfonamide unit -SO₂-NH- or its anionic form -SO₂-N^--; and, optionally • a counter-cation of the anionic form of the sulfonamide unit, chosen among the alkali metals and the proton H⁺. These compounds are of particular interest as single-ion conducting polymer electrolyte.
