Mass spectrometric studies have shown that contact-arc vaporization of polytetrafluoroethylene-containing graphite rods leads to the formation of mainly trifluoromethylated [60]-fullerenes of the general formula C,(CF,),H,,
where n = l-8 and m = O-9. Similar results were achieved by using sodium trifluoroacetate/graphite composite rods.

Single fullerene cages are generated by irradiating different carbon specimens with electrons in an electron microscope. The process is non-thermal and slow and hence accessible to direct observation. Under irradiation, lattice planes unwind from graphitic particles, bend and close by forming irregu
Exohedrally chlorinated fullerenes have been synthesized by in situ chlorination using the high-frequency furnace method in the presence of carbon tetrachloride as reagent. In addition to the previously reported chlorinated non-IPR (isolated pentagon rule) fullerene cages of C 2n Cl 2m (n = 25, 27,
## Based on an assumption that carbon caps involving hexagons and pentagons may be the intermediates in fullerene and buckytube formation processes, a theoretical study was performed on a model for the structures and closure of carbon caps. The results suggest that the carbon caps with six isolate
