Functionalized Fullerene Interactions With Transition Metals PDF Download

The research presented in this dissertation focuses of three areas in fullerene chemistry: fullerene functionalization, metal-fullerene frameworks and crystallographic studies of these materials.Fullerene functionalization is performed through di-amination of fullerene C60 and C70 in Chapter 2 and via opening and oxygenation of the cage in Chapter 4. These adducts were engineered to act as bi- or multi-dentate oxygen and/or nitrogenous ligands in the presence of Lewis acids. In order to furnish the way to metal-fullerene frameworks, two groups of Lewis acids were used; weak Lewis acids (halogens and interhalogens) and stronger Lewis acids (transition metals). In Chapter 2, the diamine functionalized fullerenes are synthesized and introduced to diiodine and iodine monochloride. This resulted in overcoming the difficulty of growing ordered single-crystals of fullerenes adducts on one side and on the other side, forming supramolecular and polymeric fullerene structures. In Chapter 3, fullerene adducts are introduced to secondary building units of transition metals. We produce linear crystalline polymers that could trap free C60 or C70 molecules between its chains. Also, 2-dimensional metal-fullerene frameworks were successfully crystallized in the self-assembly of fullerene bis-adducts ligand and rhodium acetate. In Chapter 4, we explore the coordination chemistry of open-cage fullerenes and their promises in supramolecular synthesis. These fullerenes, which were first synthesized by Murata and his co-workers, carry oxygen and nitrogenous groups. Here, we’re presenting the first crystallographically characterized dimeric and polymeric structures of open-cage fullerenes, which were formed in coordination with of silver ions. This dissertation does not cover the research that was done in collaboration with other research groups, however, a full list of publications is provided in Appendix A.
