The structures and properties of C60 under pressure

• The strong intramolecular bonds and very weak intermolecular bonds in fullerenes such as C60 lead to a strong pressure dependence in many of their physical properties and to subtle structural changes under pressure. Compression of the lattice in combination with orientational ordering also enables rather easy formation of covalent intermolecular bonds under pressure, such that treatment at high pressure and high temperature leads to the formation of several different polymeric phases. Some recent experimental results on the structure and properties of C60 under high pressure are discussed, with particular emphasis on the effects of changes in the orientational structure on the bulk modulus and the effects of polymer dimensionality on the macroscopic physical properties of C60 polymers, respectively.
