SFB 583:  Redox-Active Metal Complexes: Control of Reactivity via Molecular Architecture

• Subject Area: Chemistry ; Thermal Engineering/Process Engineering
• Term: from 2001 to 2012
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5484668

Redox reactions are a universal type of chemical reactions. Redox active metal complexes are indispensable for the majority of these reactions. The goal of this collaborative research centre is the systematic elucidation of important elementary reactions and their control via the structure of the participating metal complexes. The research projects are divided into three areas: Molecular architectures for molecule activation, Molecular architectures for charge transfer, Physical and theoretical quantification of functionality. As a first step, catalyst architectures that are able to coordinate and activate small inert molecules (N2, H2, CO, CH4, etc.) and are in turn capable of transferring electric charge will be developed. Studies on chemical reactivity, kinetic mechanistic investigations and physical measurements will elucidate quantitatively the extent of molecule activation and the amount of charge-transfer. Quantum mechanical calculations will provide microscopic details that will lead to the construction of better molecular architectures and catalytic metal complexes.
