Hurrah run derivative, resin constituent and its hardened material

摘要

PURPOSE: To obtain the subject compound capable of readily forming a thin film and extremely useful as a photocatalyst and a three-dimensional non-linear optical material. ;CONSTITUTION: The objective fullerene derivative is expressed by formula I (R₁ is a direct bond or a 1-6C alkylene bond; R₂ is H or methyl; X is S, NH, or O, etc.; Y is O or NH, etc.; (n) is an integer of 1-30; the group represented by formula II is a group wherein 1-(n) bonds among double bonds existing in the fullerene molecule become single bonds). The fullerene derivative of formula I is obtained by subjecting a compound having a functional group containing (meth)acryloyl and a functional group containing an active hydrogen besides the former functional group in the same molecule to a nucleophilic addition reaction with the fullerene. The fullerene derivative of formula I is mixed with a photopolymerization initiator and irradiated with ultraviolet rays or visible light, or mixed with a radical polymerization initiator and heated as necessary, to readily obtain a polymeric compound, and a photofunctional film may be obtained from a resin composition containing the polymeric compound.;COPYRIGHT: (C)1996,JPO
