The synthesis of biomimetic coordination compounds is a particularly fascinating area of research in bioinorganic chemistry. Related to this research field, a plethora of new transition metal complexes including the developed tetradentate phenanthroline guanidine hybrid ligands were synthesized and characterized within the present work. Particular aim was the construction of copper based electron transfer model systems that mimic the first electron transfer of cytochrome c to the CuA center of the cytochrome c oxidase. The electron transfer systems consist of an electron donor and an acceptor connected by an organic linker. In order to obtain an appropriate linker system, the phenanthroline guanidine hybrids composed of two differentiated nitrogen donor functions with biomimetic potential were synthesized. A variety of hitherto unknown mono-, bi- and tetranuclear copper, nickel and zinc complexes were synthesized for a thorough investigation of the coordination properties of the linkers. Based on this knowledge, the electron transfer systems were composed step by step. In the first step a ruthenium, respectively an iridium donor unit, which allows a photo induced electron transport, is connected to the phenanthroline side of the linker. The second step comprises the coordination of copper(II) ions at the guanidine side. By this strategy, several precursors without an acceptor unit, as well as the resulting heterobinuclear complexes, were synthesized and fully characterized. Three systems were obtained whose intramolecular electron transfer properties have been verified by fluorescence spectroscopy. These fundamental results are innovative findings for modelling the first step of the electron transport cascade within the cytochrome c oxidase.
