The research reported in this dissertation details the synthesis, preparation, characterization, and 1H-NMR and UV-vis studies of porphyrin and/or fullerene based complexes. The first chapter focuses on the splitting reaction of the oxygen bridged dimer {InIII(OEPO)} 2 (where (OEPO)3- is the trianion of octaethyloxophlorin) by potential axial ligands e.g. imidazole and pyridine. The reaction of the dimer with excess imidazole contained two different (im)2In III(OEPO) units that are bridged through hydrogen bonding by an uncoordinated imidazole. Treatment of {InIII(OEPO)}2 with an excess of pyridine (py) produced (py)2InIII(OEPO). The synthesis and single crystal X-ray structures of ClInIII(OEP), ClInIII(OEP) benzene, ClInIII(OEP) p-dioxane/benzene, ClInIII(OEP) pyridine, ClInIII(OEP) chlorobenzene, and ClInIII(OEP) C60 in benzene are reported in Chapter 2. The last two chapters is a series of cocrystallizations. Chapter 3 reports the structure of dicobalt octacarbonyl co-crystallized with C 60: Co2(CO)8*C60, as determined by single-crystal X-ray diffraction at low temperature. Chapter 4 discusses the crystallization attempts of OVII(OEP) and H2(OEP) with fullerenes [60] and [70]. In summary, this dissertation explores the reactity of {InIII(OEPO)}2 with an excess of pyridine or imidazole. It also explores ClInIII(OEP) as a "porphyrin sponge". And last, Chapters 3 and 4 provide porphyrin examples that successfully co-crystallize with fullerenes as it further studies the interactions involved.
