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.
