Abstract [en]

Prolonged hydrogenation of C60 molecules by reaction with H2 at elevated temperature and pressure results

in fragmentation and collapse of the fullerene cage structure. However, fragments can be preserved by

immediate termination of dangling bonds by hydrogen. Here we demonstrate that not only fullerene fragments

but also hydrogenated fragmented fullerenes (e.g., C58H40 and C59H40) can be synthesized in bulk amount by

high-temperature hydrogenation of C60. We confirm successful synthesis of these species by matrix-assisted

laser desorption ionization time-of-flight mass spectrometry and complete speciation of the resultant complex

fullerene mixtures by high-resolution field desorption/ionization Fourier transform ion cyclotron resonance

mass spectrometry.
