Universität Bonn - "Valence State Distribution and Mixed Valency in Ruthenium Complexes with Redox Sensitive Ligands"⠀

Synthesis of polynuclear metal complexes which can exhibit strong intermetallic electronic coupling across the bridge in the mixed valent state is a formidable challenge. Later, the focus has been shifted to the application potential of mixed-valent systems for molecular electronics. In this regard, a wide variety of mixed valent poly-ruthenium complexes have been designed using selective bridging and ancillary functionalities. Ruthenium complexes have been chosen due to their suitability and extended history for valence exchange in coordination chemistry. Our systematic approaches beyond the conventional systems by using sophisticated ligands and by creating more variegated coordination patterns have demonstrated the following fun-damental points: (i) Metal-ligand cooperativity chemistry could bring the structural miscellany in the substrate backbone. ...
