Energy is arguably the single most important problem facing humanity today. The development of cheap, efficient photovoltaic technology could dramatically change this, providing humanity with renewable, environmentally acceptable energy resources. The need to replace present electrical energy generation, largely based on fossil fuel, is without argument given the detrimental effects of global warming from increasing carbon dioxide production. The development and implementation of cheap, efficient photovoltaic technologies in Australia will not only ensure its sustainable economic growth but also contribute in a major way to the improved use of land, water, mineral and other energy resources in Australia.

Supramolecular assembly in photovoltaic electrode design: Studies of ordered porphyrin/acceptor complexes on polythiophene electrodes. This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships. As such, it addresses a problem of international concern 'How to reduce greenhouse gas emissions and stop global warming?' since s ....Supramolecular assembly in photovoltaic electrode design: Studies of ordered porphyrin/acceptor complexes on polythiophene electrodes. This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships. As such, it addresses a problem of international concern 'How to reduce greenhouse gas emissions and stop global warming?' since solar cells do not produce carbon dioxide. To achieve our goals we draw on the skills of a team of experts from Australia (synthetic organic chemists), New Zealand (polymer and surface chemists) and Italy (photochemist and photophysicist). Such research is very appropriate for regional Australia, especially Central Queensland.Read moreRead less
Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety ....Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety of electron transfer mediators can be examined in a readily controlled and systematic way simply through the choice of cation. In this way, the role played by molecular recognition in the modulation of long-range electron transfer can be evaluated. This work will lead to designing better artificial solar energy converters and molecular electronic devices.Read moreRead less
Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself tog ....Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself together. This research will use nature's light harvesting elements, namely porphyrins, and our ability to precisely control their position with respect to each other to build new, more efficient solar cells.Read moreRead less
Tailored porphyrins for nanoscience applications. Porphyrins are the pigments of life, the central components of haemoglobin in blood and chlorophyll in living plants. In order to expand their use into important areas of nanoscience, this project will establish a new porphyrin paradigm. It will result in the synthesis of novel porphyrins with inbuilt structural features that enhance their propensity to self-assemble into monolayers on surfaces, and into nanorods. This will lead to advanced mate ....Tailored porphyrins for nanoscience applications.

It will result in the synthesis of novel porphyrins with inbuilt structural features that enhance their propensity to self-assemble into monolayers on surfaces, and into nanorods. This will lead to advanced materials for molecular sensing, photonics, molecular memory devices, catalysis, and organic photovoltaics. A new means of improving the efficiency of solar cells will also be explored. Well-trained graduates and strong international scientific cooperation will also result from the project.Read moreRead less
