Synthesis of C60-NBNand C70-NBN(N=L, 2) by DC arc Burning Method

Abstract
Macroscopic quantities of boron-doped fullerenes, such as C60-nBn and C70-nBn(n = 1, 2), were successfully synthesized by DC arc burning method, extracted by CS2, and characterized by field desorption mass spectra. Among them C58B2 and C68B2 were extracted for the first time. The boron-doped fullerenes were found to be less stable than their pristine fullerene analogs. When the electric current becomes too high, no boron doped fullerene, but more higher fullerenes, were formed.
