Polyoxometalate based Metal-Organic Assemblies Towards Supramolecular Catalysis

Polyoxometalates (POMs) represent a unique class of anionic metal-oxygen clusters with special characteristics that have been extensively investigated for various applications. However, the functionalization and applications of inorganic POMs are often hampered by several drawbacks, such as limited ability to modify their structures, low pH and hydrolytic stability, and the poor solubility of most alkali-POM salts in organic solvents. With regard to this, developing supramolecular approaches in POM chemistry could greatly overcome these drawbacks and allow for POM functionalization at the molecular level leading to great tunability of their properties. This proposal aims to develop novel POM-based supramolecular architectures and to explore their potential as supramolecular catalysts in confined space. We will develop this new area of supramolecular chemistry by addressing some key design strategies that will extend both structures and functions of POMs and cage-based architectures.
