metallosupramolecular

Metallosupramolecular chemistry is a field that combines principles of both coordination chemistry and supramolecular chemistry. It focuses on the design and synthesis of large, organized structures formed through the self-assembly of metal ions or metal complexes with organic ligands. These assemblies are held together by non-covalent interactions, such as coordination bonds, hydrogen bonds, and pi-pi stacking, in addition to metal-ligand bonds.

The key feature of metallosupramolecular chemistry is the directed assembly driven by the specific coordination preferences of metal ions and the geometric constraints imposed by the organic building blocks. This allows for precise control over the final architecture, which can range from discrete molecular cages and capsules to extended polymeric networks and complex self-assembled monolayers. The metal center acts as a crucial node, directing the assembly process and imparting unique electronic, magnetic, or catalytic properties to the resulting supramolecular entity.

Applications of metallosupramolecular systems are diverse and span areas such as catalysis, molecular recognition, sensing, drug delivery, and the creation of novel materials with tailored functionalities. For example, metallosupramolecular cages can encapsulate guest molecules, offering possibilities for controlled release or protection. Metal-organic frameworks (MOFs), a prominent class of metallosupramolecular materials, possess high surface areas and tunable pore sizes, making them attractive for gas storage and separation. The ability to rationally design and construct these intricate assemblies from the bottom up is central to the advancement of this interdisciplinary field.
