CHEMICALLY MODIFIED FULLERENE AND METHOD FOR PRODUCING THE SAME, PROTON CONDUCTIVE MEMBRANE CONTAINING CHEMICALLY MODIFIED FULLERENE

摘要

A chemical fullerene derivative is for a proton conducting membrane electrolyte, in which sulfonic acid group SO3M and/or phosphonic acid group PO(OM)2 is directly bonded, but an organic compound is substantially not bonded. A production method is for the chemical fullerene derivative, which uses dimethylacetamide plus water in the case of sulfonation reagent K2SO3 and dioxane in the case of phosphonation reagent LiPO(OEt)2.
