Abstract

The recently synthesized fullerene-cubane molecular crystals constitute rotor-stator systems, where the static cubane, C8H8, occupies the octahedral interstices of the face-centered-cubic structure and acts as a bearing between the rotating fullerene molecules. C60-C8H8 undergoes a structural phase transition at around 140 K, where the rotation of the fullerenes stops. This transition temperature is significantly lower than in any other fullerene derivative. Above 400 K, a chemical reaction occurs between the constituents. Vibrational spectroscopy is ideally suited to follow these processes and determine the changes at the molecular level. I will present temperature- and pressure-dependent infrared and Raman spectra of this exciting new family of compounds.
