Abstract [en]

A large number of small hydrogenated fullerenes and unusual polycyclic aromatic hydrocarbons were detected by mass-spectrometry in samples obtained by C60 reaction with hydrogen gas at 673 K. A synthesis of a large number of sequential breakdown products instead of fast formation of amorphous carbon was found due to immediate termination of dangling bonds by hydrogen atoms during the C60 fragmentation process. This opens a possibility to synthesize these unusual materials in bulk amounts. Investigation of breakdown products could also help to select building blocks for synthesis of cage structures by purely chemical methods.
