| Sumario: | Fullerenes are closed carbon cages constituted by an even number of atoms. One of the attractive properties of the hollow carbon clusters is the possibility to use them as robust containers for other species. The first proposal of an endohedral fullerene was given only a few days after the discovery of C60. Endohedral metallofullerenes have attracted the attention of the scientific community not only because their unique host-guest behaviors, but also because the properties and, thus, the applications are significantly different from those of the empty cages. The formal electron transfer that has been found to happen between the trapped unit and the carbon cages is determinant for the understanding of these new properties. Herein we report an extensive study combining computations and experiments. This combination is a powerful tool for the structural characterization of new species. The computation of the structures and the modeling of the properties, allow us to compare the experimental and computational data to identify the new systems. In this thesis the reader will find a complete study from small endohedrals, Ti@C2n (2n=26-50) and other M@C2n, to larger fullerenes as Sc2S@C70, Sc2S@C72 and Ti2S@C78. |
