Fullerenes and Carbon Nanotubes are well known nanostructures, formed only of carbon. These materials display a variety of physical properties, such as superconductivity, magnetism, or various quantum effects. A great advantage of these carbon nanostructures is that the unit structures are well defined, in sharp contrast to the broad size distributions of inorganic clusters. In this article, solid state properties of fullerenes are reviewed with particular interest in the correlation between the molecular rotation and electric/magnetic states. Firstly, dielectric properties of metal encapsulating fullerene La@C_<82> is presented. Because of the polar nature of the molecule and the molecular rotations, the La@C_<82> solids are dielectric active. Dipolar functionality gives an important handle that maybe of use in developing potential molecular or solid state devices. Secondly, we show that the intermolecular magnetic interactions in the C_<60> magnets are controlled by the relative orientations of neighboring molecules. The correlation between magnetic interaction and molecular orientation provides an important analogy to the transition metal oxide magnets.
