Tartalmi leírás:
A new family of heteromolecular crystals has been described recently: the rotor-stator phases of fullerenes with cubane. Cubane (C(8)H(8)), the stator component of these materials is a highly strained molecule which decomposes to higher stability C(8)H(8) hydrocarbons at 200 degrees 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 degrees 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.
