Abstract
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.
Claims8
A method for producing a partially halogenated, hydroxylated fullerene represented by the following general formula of CpXn(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, hydroxylated fullerene having the halogen group and the hydroxyl group at a ratio of 1:71 to 1:1 (halogen group:hydroxyl group),
- wherein p represents an even number of 60 or more,
- X represents a halogen group,
- n represents a number of more than 0 and up to 48, and
- m represents a number of more than 9 and up to 44.
A method for producing a partially hydroxylated, halogenated fullerene represented by the following general formula of CpXn(OH)m, comprising halogenating a fullerene nucleus of a hydroxylated fullerene having a hydroxyl group bonded to the fullerene nucleus, and controlling reaction conditions such that a part of the hydroxyl groups still remain bonded to the fullerene nucleus following said halogenating, thereby producing a partially hydroxylated, halogenated fullerene having the halogen group and the hydroxyl group at a ratio of 1:71 to 1:1 (halogen group:hydroxyl group),
- wherein p represents an even number of 60 or more,
- X represents a halogen group,
- n represents a number of more than 0 and up to 48, and
- m represents a number of more than 9 and up to 44.
A method for producing a partially hydroxylated, chlorinated fullerene represented by the following general formula of CpXn(OH)m, comprising chlorinating a fullerene nucleus of a hydroxylated fullerene having only a hydroxyl group bonded to the fullerene nucleus, and reacting the hydroxylated fullerene with iodine chloride such that a part of the hydroxyl groups still remain bonded to the fullerene nucleus following said chlorinating, thereby producing a partially hydroxylated, chlorinated fullerene having the chloro group and the hydroxyl group at a ratio of 1:71 to 1:1 (chloro group:hydroxyl group),
- wherein p represents an even number of 60 or more,
- X represents a chloro group,
- n represents a number of more than 0 and up to 48, and
- m represents a number of more than 9 and up to 44.
