Provided are a novel fullerene derivative which can adsorb quickly and efficiently an allergen which may cause a pollen allergy without releasing the allergen again, does not contain a metal or the like which may cause a harmful effect to a human body, and is easily applicable, impregnable, or chemically bondable onto surface of various materials; and a process for producing the same. The fullerene derivative is characterized in that a halogen group and many hydroxyl groups are bonded directly to a fullerene nucleus. In the case that the halogen group is chlorine, the fullerene derivative can be synthesized by a partial hydroxylation of a chlorinated fullerene or a partial chlorination of a hydroxylated fullerene.

A method for producing a fullerene derivative, characterized in that bonding of a hydroxyl group to a fullerene nucleus of a halogenated fullerene having a halogen group bonded to the fullerene nucleus is made such that a part of the halogen groups still remain, thereby producing a partially halogenated, hydroxylated fullerene.
A method for producing a fullerene derivative, characterized in that bonding of a halogen group to a fullerene nucleus of a hydroxylated fullerene having a hydroxyl group bonded to the fullerene nucleus is made such that a part of the hydroxyl groups still remains, thereby producing a partially halogenated, hydroxylated fullerene.
A method for producing a fullerene derivative, characterized in that bonding of a chlorine to a fullerene nucleus of a hydroxylated fullerene having a hydroxyl group bonded to the fullerene nucleus is made by reacting the hydroxylated fullerene with iodine chloride such that a part of the hydroxyl groups still remain, thereby producing a partially chlorinated, hydroxylated fullerene.
