摘要：

Differential scanning calorimetry has revealed the presence of an endothermal process at 150.0+/-0.5 K in the p-tert-butylcalix[8]arene(1:1)C-60, that is not associated with a structural change or a discontinuity. We attributed this event to a new orientational transition which is different from that in pristine C-60. At low-temperature, some change in the axis of reorientation of solvated C-60, molecules may be due to an interaction between C-60 and CH3 groups of the solvate, related with an unknown conformation of CH3 in the host.
