Ion-Dissociative Functional Compound, Method for Production Thereof, Ionic Conductor, and Electrochemical Device |
摘要 |
Disclosed herein are an ion-dissociative functional compound, a method for production thereof, an ionic conductor, and an electrochemical device, the ion-dissociative functional compound being thermally and chemically stable under the condition required of fuel cells and being suitable for use as a material such as protonic conductor in fuel cells. The proton-dissociative functional compound shown in FIG. 1A is composed of a fullerene C60 molecule and about 10 sulfonic acid groups -SO3H as proton-dissociative groups each attached to the fullerene through a difluoromethane group -CF2-. The proton-dissociative functional compound shown in FIG. 1B is composed of fullerene molecules three-dimensionally connected to each other through a linking group -CF2SO2NHSO2CF2-. It contains, as the proton-dissociative group, sulfoneimide groups -SO2NHSO2- and sulfoneamide groups -SO2H2 in addition to sulfonic acid groups. These compounds are prepared by introduction of difluoro(fluorosulfonyl)methyl groups into fullerene molecules, and ensuing imidization and hydrolysis. |
