Self-assembled supramolecular cages for guest binding and catalysis. This project aims to construct a family of supramolecular metal-containing cage-shaped molecules that possess specialised binding pockets with unique chemical properties that mimic enzymes. Many existing cage molecules contain well-defined three dimensional cavities reminiscent of enzymes' active sites. However, unlike natural systems they do not contain "active" metals with free coordination sites, and this limits their cataly ....Self-assembled supramolecular cages for guest binding and catalysis. This project aims to construct a family of supramolecular metal-containing cage-shaped molecules that possess specialised binding pockets with unique chemical properties that mimic enzymes. Many existing cage molecules contain well-defined three dimensional cavities reminiscent of enzymes' active sites. However, unlike natural systems they do not contain "active" metals with free coordination sites, and this limits their catalytic ability. This project aims to prepare a large family of robust organic cages quickly and easily, and subsequently incorporate metals containing free active sites that point into the cage cavity. It is expected that this will deliver strong and selective guest binding, and efficient and selective catalysis.Read moreRead less
Responsive Metal-organic Framework Glass Membranes for Molecular Sieving. Metal-organic frameworks are an important category of microporous materials, showing extraordinary structural and chemical diversities. The recent discovery of their melting behaviours endows these materials with high processability, enabling the transformation of crystal powders into mechanically durable microporous bulk glasses for device assembly. This project aims to understand the melting and modification mechanism, a ....Responsive Metal-organic Framework Glass Membranes for Molecular Sieving. Metal-organic frameworks are an important category of microporous materials, showing extraordinary structural and chemical diversities. The recent discovery of their melting behaviours endows these materials with high processability, enabling the transformation of crystal powders into mechanically durable microporous bulk glasses for device assembly. This project aims to understand the melting and modification mechanism, and to incorporate responsive moieties to the glass. It further aims to realise switchable membrane separation for gas mixtures. This project is expected to enhance the understanding and application of these emerging glass materials and promote Australia’s capability in value-added manufacturing of metal minerals.Read moreRead less
Mixed-Metal Clusters for Catalysis and Optical Applications. This project aims to afford new heterometallic molecular materials as precursors to catalysts and as new optical materials, exploiting oxophilic and carbophilic transition metal atoms for synergistic cooperation in certain catalytic processes, and using the polarity of heterometallic bonds to achieve strong optical limiting. Expected outcomes of this project include cluster structure/composition - catalysis/optical properties correlati ....Mixed-Metal Clusters for Catalysis and Optical Applications. This project aims to afford new heterometallic molecular materials as precursors to catalysts and as new optical materials, exploiting oxophilic and carbophilic transition metal atoms for synergistic cooperation in certain catalytic processes, and using the polarity of heterometallic bonds to achieve strong optical limiting. Expected outcomes of this project include cluster structure/composition - catalysis/optical properties correlations that will signpost the route to efficient catalysts and optical limiters. This Project should provide significant benefits such as chemoselective catalysts needed for pharmaceutical drug and agricultural chemical production, and broad temporal range optical limiters needed for optical device protection.Read moreRead less
