Polyphenols, these plant-derived natural products, were traditionally referred to as vegetable tannins, due to their original use in the industrial process of tanning to convert animal hide into leather. This speaker will discuss the possibility to exploring the unique physicochemical and biological properties of polyphenols to serve as an important source of inspiration in the search for new and improved materials. A library of functional metal-phenolic network (MPN) nanostructured films and capsules was prepared from the coordination between a phenolic ligand and a range of metal ions. Furthermore, the polyphenol-based particle functionalization was discovered to facilitate an interfacial molecular interaction-induced self-assembly process. This allowed for the generation of a highly versatile and effective methodology to prepare a large variety of superstructures assembled from a wide range of building blocks. This method displayed significant versatilities of sizes, shapes, microstructures, and compositions as building blocks. The generic nature of this method led to a large family of modularly assembled superstructures including core-satellite, hollow, and hierarchically organized supraparticles. Colloidal-probe atomic force microscopy and molecular dynamics simulations provided detailed insight into the role of this polyphenol-based particle functionalization and how this functionalization facilitated superstructure construction. In functional aspects, the polyphenol-based materials were tailored for advanced drug delivery, positron emission tomography (PET), magnetic resonance imaging (MRI), catalysis, and electromagnetic (EM) applications.
