Abstract

A new family of heteromolecular crystals has been described recently: the rotor-stator phases of fullerenes with cubane. Cubane (C8H 8), the stator component of these materials is a highly strained molecule which decomposes to higher stability C8H8 hydrocarbons at 200°C. This unimolecular isomerization takes also place in the rotor - stator phases, inducing a single phase topochemical reaction with the surrounding fullerenes. The resulting material is a random copolymer, percolating in the primitive cubic sublattices of the parent crystals. We followed the polymerization by HPLC, IR and UV - VIS spectroscopy, and determined the thermal stability by TG-MS analysis. The polymers are insoluble, and stable up to 400°C. At this temperature they start to decompose while preserving their crystalline appearance. The influence of the side groups of substituted cubanes on the polymerization will also be discussed.
