Complementary pairs for next generation self-assembled systems . This project will employ a set of complementary pairings where separate sites fit together at metal ions in a specific fashion orthogonal to other pairings, like two jigsaw pieces, while forming a poor fit with other pairings. These pairings will allow retention and transfer of structural information. In this way, the bulk combination of relatively simple precursors will lead to self-assembled structures with well-defined seque ....Complementary pairs for next generation self-assembled systems . This project will employ a set of complementary pairings where separate sites fit together at metal ions in a specific fashion orthogonal to other pairings, like two jigsaw pieces, while forming a poor fit with other pairings. These pairings will allow retention and transfer of structural information. In this way, the bulk combination of relatively simple precursors will lead to self-assembled structures with well-defined sequence identity. This program will make and use complex abiotic molecules, enhancing outcomes in molecular information storage and transfer, molecular recognition and sensing, chemical transformations, and energy transport events, leading to economic and environmental benefits for Australia in industry and manufacturing.Read moreRead less
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

A New Breed of Metallosupramolecular Assembly. Self-assembly is the ready formation of complex structures from simple components. Nature uses this to generate its most impressive molecular machinery to carry out complex tasks. Metallosupramolecular chemists combine simple components (metal ions and organic ligands) to create synthetic variants to fulfil similar roles.

Self-assembly is the ready formation of complex structures from simple components. Nature uses this to generate its most impressive molecular machinery to carry out complex tasks. Metallosupramolecular chemists combine simple components (metal ions and organic ligands) to create synthetic variants to fulfil similar roles. Current methods have limitations, and this project aims to create a new structural type: large and controllably variable metallo-foldamers (structures consisting of metal ions and ligands that coil like DNA). As well as benefiting fundamental knowledge, these molecules will be functional. They are expected to improve performance with enhanced outcomes in photophysical, photochemical, catalytic, and sensing applications.Read moreRead less

This project aims to create nano-fibrous active thin films with high charge mobility for organic photovoltaic (OPV) devices, using a method inspired by molecular gelation. The significance of this project is that it addresses a major bottleneck, i.e. poor charge generation and transport, that limits the efficiency of OPV devices. The outcomes will provide insights into the crucial factors that affect the self-assembly of organic semiconducting materials, and the influences of nano-fibrous structure on the charge mobility and efficiency of an OPV device. The outcomes will greatly facilitate the development of highly efficient, lightweight and low-cost solar energy harvesting devices to reduce our carbon footprint.Read moreRead less

Boryl Pincers and Beyond: Taming Borometallic Chemistry. Industrial applications of coordination complexes in catalysis reduce energy input and environmental impact but almost exclusively involve classical donors such as nitrogen, oxygen, sulfur and phosphorus. Boron, whilst prevalent and environmentally benign, is under-utilised in such applications, in part due to the high reactivity of the metal boron bond.
