Abstract

The parameters of an electric-arc facility for the synthesis of fullerenes and endohedral metallofullerenes are optimized. The resistance of С60 and С70 fullerenes and С60(ОН)30 and С70(ОН)30 fullerenols against neutron irradiation is studied. It is established that the radiation resistance of the fullerenes is higher than that of the fullerenols, but the radiation resistance of the Gd@C2n endometallofullerenes is lower than that of the corresponding Gd@C2n(OH)38 fullerenols. The radiation resistance of mixtures of Ме@C2n(OH)38 (Me = Gd, Tb, Sc, Fe, and Pr) endometallofullerenes with C60(OH)30 is determined. The factors affecting the radiation resistance of the fullerenes and fullerenols are discussed.
