Functionalised metal complexes for tuning their surface enrichment and reactivity at ionic liquid interfaces (B02)

• Subject Area: Inorganic Molecular Chemistry - Synthesis and Characterisation
• Term: from 2021 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 431791331

We aim to design functionalised redox active metal complexes to control their enrichment and orientation at ILs interfaces, i.e. the exposure of active sites to the reactants and thus, control their reactivity. Targeted will be binding and hydrogenation/reduction of CO2 or other C=O functionalities by Pt, Pd, Ru and Ni complexes of bi-, tri- and tetradentate pincer-like or macrocyclic ligands. Systematic variation of substituents will tune charge, polarity, coordination equilibria and redox properties of complexes, affecting interactions with ILs and reactants, leading to catalytic activity. We will also study kinetics and thermodynamics of processes in ILs and, for comparison, conventional solvents by variety of techniques, including high-pressure and cryo-methodology.
