- The translational and orientational structures of fullerenes are very sensitive to pressure, p, because of the weak intermolecular potentials. We have recently carried out high-p studies of the thermal conductivity lambda and the bulk modulus B of C60 and C70, and we show here how the p-T phase diagrams of these materials can be mapped from data for B and lambda and a knowledge of the structures at zero pressure. We discuss how B and lambda are modified by translational, rotational and orientational disorder in the materials, mainly showing examples related to the orientational substructure and its evolution with T and p in C60. We also discuss briefly the structures and phase diagrams of C70 and C61H2, and we show preliminary experimental results suggesting that the structure of high-p, high-T treated C60 is probably not polymeric as recently suggested by several groups.
