Hierarchically structured coordination oligomers that are linked covalently to a strongly electron-accepting moiety (e.g. fullerenes or polyoxometalates) are in the focus of interest, since these photoactive materials are reminiscent of green plants photosystem (PS-II). Long-living charge-separated states play a crucial role in many natural processes, e.g. photosynthesis. Artificial systems mimicking nature's examples are of relevance for the development of applications related to light-to-energy conversion (i.e. photovoltaics, photocatalysis).Aiming for a fundamental understanding of the energy and/or electron transfer processes within the targeted assemblies, the synthesis of diverse molecular subunits and the spectroscopic characterization thereof is of utmost importance.In order to enable highly directed transfer processes within linear ensembles, we rely on established rigid terpyridine-based systems. In this contribution, we report on the synthesis and spectroscopic investigation of bi- and trinuclear complexes of such terpyridine derivatives with various transition metal ions (i.e. RuII, OsII, FeII, IrIII).
