Development of N-heterocyclic carbene ligands for nanomaterials in aqueous media and expanding the interface of metal-organic framework (MOF) and polymer chemistry via polyMOFs
… surface modification and (2) metal-ligand driven supramolecular assembly. (1) Surface ligands are typically used for surface passivation, imparting new properties such as solubility, or introducing a functional handle for further modification. The different demands in many diverse fields such as …
