Work package:
Enzymes are extremely powerful catalysts for a large variety of biological reactions. For a long time, chemists have sought to reproduce such activities using supramolecular cages as artificial enzymes. The interior cavity of these cages mimics enzyme pockets and can host reactions.[1] The confinement of reacting molecules within these cavities changes their original reactivity: indeed, noticeable impact on both rate and selectivity has been evidenced. In the framework of this project we aim to study and develop the reactivity of transition metal complexes (particularly gold) within confined environments.[2] Our group has a strong interest and experience in gold chemistry, that we wish to further develop in a supramolecular context.[3] In summary, the objective of this project is to design and synthesize novel, anionic supramolecular cages that will be used to confine reactive, cationic gold complexes.
