The goal of this supramolecular research is to synthesize both symmetric and asymmetric molecules which will serve as the central ligation point of more advanced transition metal/fullerene systems. The symmetric center will allow for rapid production of these systems, while the asymmetric center will allow for the production of more complex systems with differing moieties on each side of the center. A detailed description of the reaction mechanisms involved, as well as refinements to existing methodologies for these Sonogashira and Stille coupling reactions, will be presented. The symmetric center has been completed and utilized in the fullerene systems, while the asymmetric system is still being optimized. With successful isolation of the asymmetric molecule, further research will focus on attachment of fullerenes to this center, as well as their incorporation into other areas of our supramolecular photochemical research.
