Nanomaterials: Probing supramolecular self-assembly at the solution/solid interface. Australia's competitiveness in nanotechnology must be underpinned by fundamental innovation and research. In a "bottom-up" approach to nanomaterials, it is important to understand, for the smallest possible machines that can be produced, how singular molecular components interact with one another, both during the assembly of any device and afterwards as it performs its function. For working devices the molecule ....Nanomaterials: Probing supramolecular self-assembly at the solution/solid interface. Australia's competitiveness in nanotechnology must be underpinned by fundamental innovation and research. In a "bottom-up" approach to nanomaterials, it is important to understand, for the smallest possible machines that can be produced, how singular molecular components interact with one another, both during the assembly of any device and afterwards as it performs its function. For working devices the molecules need to be assembled on a solid surface so that they can work in unison. In this project, in conjunction with researchers at the University of Cambridge, we use the new technique of gel-phase NMR spectroscopy to understand the factors involved as molecular components assemble on the surface of polystyrene beads.Read moreRead less
Novel Synthetic Receptors For Selective Recognition of Phosphate Oxoanions. Anions are critical to the maintenance of life, playing roles in almost every biochemical process. Artificial anion receptors that bind strongly to specific anions have considerable potential applications in biomedicine, but current receptors do not possess the required selectivity for applications. We will undertake the design and construction of a number of molecular receptors tailored to complement the size, shape and ....Novel Synthetic Receptors For Selective Recognition of Phosphate Oxoanions. Anions are critical to the maintenance of life, playing roles in almost every biochemical process. Artificial anion receptors that bind strongly to specific anions have considerable potential applications in biomedicine, but current receptors do not possess the required selectivity for applications. We will undertake the design and construction of a number of molecular receptors tailored to complement the size, shape and charge of specific biologically important anions and will assess their ability to bind selectively to their target guests. This will lead to the development of small molecule receptors for use in biomedical applications.Read moreRead less
Backbone Modified Cyclic Peptides: Scaffolds for Supramolecular Chemistry. The synthesis of compounds that mimic Nature's catalysts - enzymes - will provide us with a better understanding of how these intriguing molecules function and may lead to the development of new catalysts for industrial processes. Modified cyclic peptides could be used as platforms to arrange catalytic groups in a spatially well-defined manner to mimic enzymes.

The synthesis of compounds that mimic Nature's catalysts - enzymes - will provide us with a better understanding of how these intriguing molecules function and may lead to the development of new catalysts for industrial processes. Modified cyclic peptides could be used as platforms to arrange catalytic groups in a spatially well-defined manner to mimic enzymes. As cyclic peptides are often difficult to prepare, I aim to develop a powerful general method for their synthesis. This methodology will then be applied to the synthesis of cyclic peptide-based enzyme mimics.Read moreRead less
SENSORS FOR AROMATIC MOLECULES BASED ON METAL ION ACTIVATED MOLECULAR RECEPTORS. This project aims to develop highly sensitive chemical sensors for aromatic compounds which will quantify their concentration, in situ, without elaborate sample preparation or instrumentation. The sensors will employ advanced supramolecular chemistry in which the aromatic molecule becomes trapped within a binding cavity in the three dimensional structure of a larger receptor molecule. Coincident with the entrapmen ....SENSORS FOR AROMATIC MOLECULES BASED ON METAL ION ACTIVATED MOLECULAR RECEPTORS. This project aims to develop highly sensitive chemical sensors for aromatic compounds which will quantify their concentration, in situ, without elaborate sample preparation or instrumentation. The sensors will employ advanced supramolecular chemistry in which the aromatic molecule becomes trapped within a binding cavity in the three dimensional structure of a larger receptor molecule. Coincident with the entrapment a change in the fluorescence level of the receptor occurs which signals the presence of the aromatic compound and its concentration. This research will stimulate economic and social benefits through the development of new environmental and medical sensing techniques and analytical diagnostics.Read moreRead less
