The longer gold complexes will behave as insulated nanowires, and are an exciting prospect for the development of nanotechnological devices. The shorter silver and gold complexes are expected to have significant antitumour properties. This project, which will use a unique theoretical-experimental approach to design the stereoregular polyphosphines, will enhance Australia's international scientific reputation, and will contribute to technological advancement in the national priority areas of nanotechnology and biotechnology.Read moreRead less
Towards Nano-circuits: 2 and 3-Dimensional Carbon-Wired Nano-architectures. Whilst Australia has a world-class profile in organotransition metal chemistry, main-group chemistry is under-represented, despite the enormous technological importance of materials based on these elements. In addition to the fundamental breakthrough science to be explored, the project will provide a training vehicle for 5 young scientists in both main group and organometallic chemistry. The target compounds involve an e ....Towards Nano-circuits: 2 and 3-Dimensional Carbon-Wired Nano-architectures. Whilst Australia has a world-class profile in organotransition metal chemistry, main-group chemistry is under-represented, despite the enormous technological importance of materials based on these elements. In addition to the fundamental breakthrough science to be explored, the project will provide a training vehicle for 5 young scientists in both main group and organometallic chemistry. The target compounds involve an essentially unique marriage of the fields of main-group and transition metal chemistry to provide complex nano-architectures based on the modular interconnection of metals and non-metals by carbon wires at the molecular level - nanoscopic counterparts of macroscopic circuit components.Read moreRead less

Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals.

Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals. Whilst Australia boasts an emergent boron-based fine chemicals industry, no research program into the nature of metal boron bonding exists to provide either fundamental science or advanced training in organometallic boron chemistry. The proposed work offers two distinct national benefits: The maintenance of a discipline in which Australia leads the world (metallaboratranes) and the genesis of one, which whilst intensely studied elsewhere, is notably absent from the Australian science base (low coordinate, unsaturated boron chemistry).Read moreRead less
Earth Abundant Metal Complexes for Nitrogen Activation. This project aims to develop a range of complexes based around earth abundant metals that are capable of activating nitrogen (N2) at ambient pressure and temperature.

This project aims to develop a range of complexes based around earth abundant metals that are capable of activating nitrogen (N2) at ambient pressure and temperature. The project expects to generate new knowledge in the area of organometallic chemistry, specifically with regards to molecular metal-metal bonding and subsequent reactivity towards the activation of nitrogen. The activation of atmospheric nitrogen is performed on a multi-million tonne scale each year and is key to a number of industrial processes. As such, investigations into new and improved catalysts for this process would potentially bring huge financial benefits to industry, as well as benefiting the environment by reducing energy demand and associated climate change.Read moreRead less
Metallaboratranes: Soft Scorpionates and Masked Metal Bases. All molecular metal compounds involve a metal surrounded by a group of electron donors (?ligands?). The design and manipulation of these ligand sets and their interactions with metals (?coordination chemistry?) underpins ALL applications of metals, be they in biological, pharmaceutical, materials or industrial applications.

All molecular metal compounds involve a metal surrounded by a group of electron donors (?ligands?). The design and manipulation of these ligand sets and their interactions with metals (?coordination chemistry?) underpins ALL applications of metals, be they in biological, pharmaceutical, materials or industrial applications. This proposal addresses the diametric opposite - the role-reversal wherein a metal centre acts as an electron donor to a ligand. This rare situation has only recently been firmly established in this research group, but promises to be part of a wider new coordination chemistry, the limits of which will be pursued in the proposed work.Read moreRead less
Borametallacycles: confluence of metallacycle and boracycle chemistries. Metallacycles are cyclic structures constructed from a transition metal and the first row elements, such as carbon, nitrogen and oxygen. They underpin numerous technological applications in catalysis and materials chemistry. Borametallacycles which include the missing element boron will be explored with a view to developing new materials with novel properties.
One coordinate carbon and boron: Universal progenitor ligands. Compounds with bonds between metals and carbon (organometallic chemistry) underpin innumerable important industrial processes from fine chemicals to bulk agrochemical and polymer synthesis. Yet the simplest example, a single atom of carbon bound to a metal has only recently been discovered and is poorly understood. Australia's fledgling boron fine chemicals industry similarly benefits from metal-based processes. However, compounds wi ....One coordinate carbon and boron: Universal progenitor ligands.

Yet the simplest example, a single atom of carbon bound to a metal has only recently been discovered and is poorly understood. Australia's fledgling boron fine chemicals industry similarly benefits from metal-based processes. However, compounds with a single boron atom bound to a metal remain unknown. This proposal addresses metal-carbon and metal-boron chemistry from the most basic perspective, that of a single atom of boron or carbon, including the development of novel synthetic approaches and skills for the characterisation of such curious species.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.

Bimetallic carbidos: hard-wiring a single atom of carbon. This project aims to explore the design, synthesis, characterisation and applications of novel materials in which metals are bridged by a single carbon atom. Materials based on metals (M) separated by a single oxygen atom (O) underpin all manner of technologies from the pigments of antiquity to modern electronics.

This project aims to explore the design, synthesis, characterisation and applications of novel materials in which metals are bridged by a single carbon atom. Materials based on metals (M) separated by a single oxygen atom (O) underpin all manner of technologies from the pigments of antiquity to modern electronics. Electronic/magnetic communication across MOM bridges is thus extremely well understood. Materials with two metals bridged by one carbon atom (MCM) are in contrast, rare and poorly understood. Developing synthetic routes to such materials will make it possible to map the diversity of chemical and electronic features against theoretical models in search of new materials with unique reactivities and properties for commercial exploitation.Read moreRead less
