摘要:
A method for preparing a fullerene derivative, wherein a fullerene derivative having a group capable of liberating a proton introduced to a carbon atom constituting the fullerene molecule is formed by using a halogenated fullerene formed by halogenating a fullerene molecule as a precursor; a method for preparing a polymerized fullerene derivative, wherein a plurality of fullerene molecules are reacted with an aromatic compound molecule to form a polymer comprising a plurality of fullerene molecules which are bound to one another via the aromatic group of the aromatic compound; a novel and useful proton conductor obtained by using the method; and an electrochemical device, such as a fuel cell, using the proton conductor. The above methods allow the efficient preparation of a fullerene having OH groups or SO3H groups such as fullerenol suitable as a proton conductor. A fullerene derivative prepared by these production methods acts as a proton conductor. The electrochemical device is free from the restriction of atmosphere and thus can be miniaturized and simplified.

摘要:
Provided are a method of efficiently procuding fullerene into which a OH group or a SO 3 H group is introduced, such as fullerenol, or a derivative thereof, the fullerene and its derivative being preferable as a proton conductor, and a novel and usable proton conductor obtained by the method. Further, provided is an electrochemical device using the proton conductor such as a fuel cell or the like. In the producing method of the fullerene derivative, halogated fullerene, which is obtained through halogating a fullerene molecule is used as a precursor, the fullerene derivative is produced through introducing one or more proton dissociative group into at least one carbon atom of a fullerene molecule. Moreover, in a producing method of a polymerized fullerene derivative, a plurality of fullerene derivatives are bonded to one another by an aromatic group of an aromatic compound through reacting the plurality of fullerene derivatives with the aromatic compound. The fullerene derivative obtained by any of these method functions as a proton conductor, and an electrochemical device using the proton conductor such as a fuel cell can be downsized and simplified without atmosphere constraints.
