Abstract

C-60 center dot CgHs and C-70 center dot C8H8 are prototypes of rotor-stator cocrystals. We present infrared and Raman spectra of these materials and show how the rotor-stator nature is reflected in their vibrational properties. We measured the vibrational spectra of the polymer phases poly(C60C8H8) and Poly(C70C8H8) resulting from a solid-state reaction occurring on heating. On the basis of the spectra, we propose a connection pattern for the fullerene in Poly(C60C8H8), where the symmetry of the C-60 molecule is D-2h. On illuminating the C-60-C8H8 cocrystal with green or blue light, a photochemical reaction was observed leading to a product similar to that of the thermal polymerization.
