Abstract:

The negative ion time-of- flight mass spectra of C60 benzyl derivative and C60/polystyrene mixtures were investigated by UV laser desorption. We found that the aggregation of C6o in derivatives and ndt1lres was very different. The mechanisms of the coalescence of C6o and the growth of C60 by capturing small carbon clusters were discussed. We thought that in derivatives the nascent C60 formed from the rupture of the radicals can easily coalesce into large fullerenes through co1lisions, while in mixtures C60 and small carbon clusters can grow into large fullerenes only when C60 and small carbon clusters were in proper ratio, but no coalescence of C60 was observed.
