Resumen:
This thesis is divided in two different parts. The first part includes the design, synthesis and characterization of a series of porphyrin trimeric receptors as well as the study of the inclusion complex formation with fullerenes (C60, C70, C84, Sc3N@C80), carbon nanotubes (CNT) and bucky onions. The main objective of this first bloc is the preparation of porphyrin-based receptors able to selectively encapsulate big fullerenes (>C84) as well as carbon nano onions (CNOs) and carbonnanotubes (CNT). The second part of the thesis deals with the synthesis and studies of a chiral pyramidic monomer bearing a CTV central core connected to long alkyl chains through urea type linkers. The objective of this second block would be the preparation of a CTV-monomer able to transfer the chirality from the CTV central core to the supramolecular column. To promote such behavior, the monomers are provided with urea moieties that due to their high specificity and directionality would promote de formation of the macroscopic helix.
