Structures, phase transitions and orientational properties of the C60 monomer and polymers
Acta Cryst. (2005). A61, 62–76
The high symmetry and round shape of the fullerene molecules induce orientational phenomena that play an important role in the properties of the fullerene compounds. This is illustrated in this review, which is focused on the orientational properties of C
60 monomer and polymer structures. The peculiar pressure–temperature orientational phase diagram of pristine C
60 is first described. Then, the polymerization processes and the various structures obtained under high-pressure high-temperature conditions or via doping by alkali metals are summarized.
