Abstract:
The thermal properties of C60 and C70 fullerenes and fullerites have been studied via X-ray structural analysis and UV spectroscopy. It was shown that C70 fullerite is stabler than C60 fullerite (by ∼150∘C) due to the different geometry of the fullerenes and stronger intermolecular interactions. The experimental results are given a qualitative and quantitative interpretation based on the calculation of the interaction energy between two fullerene molecules.
