摘要
The hypothesis that fullerenes grow in a carbon plasma by the addition of C-2 units (the "fullerene road") has been widely acclaimed as the most plausible mechanism for formation of larger fullerenes including C-60 and C-70 Calculations suggest that the association of C2 With fullerenes proceeds through two classes of intermediates, "sticks" and "handles." Here we report the observation of these species using high-resolution ion-mobility measurements for C-n cations generated by laser vaporization of graphite and laser desorption of C-60 Sticks With UP to eight-atom chains have also been found.
