N. Dragoe et al., Thermal decomposition of fullerene derivatives - A synthesis method of newfullerene based molecules, J THERM ANA, 56(1), 1999, pp. 167-173
The thermal decomposition of methano-fullerene derivatives such as ethoxyca
rbonyl methano[60] fullerene and various isomers of bis-(ethoxycarbonyl met
hano)[60] fullerene leads to new fullerene derivatives, which have been pre
liminary characterized. The analysis of separated species was performed by
UV-VIS, IR, H- and C-NMR, STM, FAB, LDI and MALDI-TOF MS spectroscopy. One
of the isolated phases is a C-122 molecule with a dumbbell-like structure.
