Synthesis and radiation resistance of fullerenes and fullerene derivatives

Аннотация

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@C_2n endometallofullerenes is lower than that of the corresponding Gd@C_2n(OH)₃₈ fullerenols. The radiation resistance of mixtures of Ме@C_2n(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.
