The formation of all-carbon [60]fullerene derivatives was observed in the c
ourse of the thermolysis of methano-fullerene derivatives. IR, UV-Vis, GPC,
C-13-NMR, TG-MS, TOF-MS and STM data are consistent with the formation of
all-carbon [60]fullerene oligomers without a direct connection between full
erene cages but through one or two carbon atoms as bridges. Molecular masse
s up to 8000 amu have been detected by mass spectroscopy.
