Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a partially halogenated, hydroxylated fullerene represented by the following general formula of C p X n (OH) m comprising hydroxylating a fullerene nucleus of a halogenated fullerene having a halogen group bonded to the fullerene nucleus, and controlling reaction conditions such that a part of the halogen groups still remain bonded to the fullerene nucleus following said hydroxylating, thereby producing a partially halogenated, h…
