IONICALLY DISSOCIATIVE FUNCTIONAL MOLECULES, PROCESSES FOR PRODUCTION THEREOF, IONIC CONDUCTORS, AND ELECTROCHEMICAL EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2005/012239

Kind Code:

A1

Abstract:

Provided are ionically dissociative functional molecules which are thermally and chemically stable under the conditions required for electrochemical equipment and useful as the material of protonic conductors of fuel cells; processes for the production thereof; ionic conductors; and electrochemical equipment. In the proton-dissociating functional molecule shown in Fig. 1A, about ten proton-dissociating sulfonic acid groups are bonded to C₆₀ fullerene through difluoromethylene (-CF₂-) groups. In the proton-dissociating functional molecule shown in Fig. 1B, fullerene molecules are connected to each other through connecting -CF₂SO₂NHSO₂CF₂- groups in three dimensions, and not only sulfonic acid groups but also sulfonimide (-SO₂NHSO₂-) groups and sulfonamide (-SO₂NH₂) groups are contained in the connected molecules. These molecules are synthesized by the introduction of difluoro(fluorosulfonyl)methyl (-CF₂SO₂F) groups into fullerene, imidation of the groups, and hydrolysis of the resulting product.
