A C 60 derivative, benzylaminofullerene (BZAF) with a stoichiometry of [C 60H 1.9(NHC 6H 5) 1.9] was synthesized by nucleophilic addition of fullerene with benzylamine in DMSO/o-dichlorobenzene. Free radical copolymerization of BZAF with methyl methacrylate or ethyl methacrylate gave high yields of copolymers. The optical limiting threshold of BZAF is comparable with that of C 60 and stronger than those of the copolymers.
