Photoredox catalysis promises sustainable alternatives to synthesise high-value chemicals using energy converted from visible light. The project aims to address the current lack of understanding about how these reactions operate at the molecular level, using innovative electrochemical and spectroscopic techniques. The expected outcomes include new catalytic systems containing multiple light-driven steps that provide reactivities beyond those attainable in single-photon cycles. These will be applied to challenging modifications of large biomolecules under mild aqueous conditions. Anticipated benefits include adding value to Australia’s growing chemical industry through efficient green syntheses with reduced dependence on toxic solvents.Read moreRead less

THE FIRST DEVELOPMENT OF MULTI-DIMENSIONAL SPECTRO-ELECTROCHEMISTRY AND ITS APPLICATION TO CRUCIAL TRANSFORMATIONS IN INORGANIC SYSTEMS. Electrolysis is a very widespread and efficient method of chemical synthesis both in industry and research. However, the link between the control voltage and the resultant current is often complicated and easily misinterpreted. To overcome this fundamental problem, we propose an optical spectro-electrochemistry instrument based on a two-dimensional CCD detectio ....THE FIRST DEVELOPMENT OF MULTI-DIMENSIONAL SPECTRO-ELECTROCHEMISTRY AND ITS APPLICATION TO CRUCIAL TRANSFORMATIONS IN INORGANIC SYSTEMS. Electrolysis is a very widespread and efficient method of chemical synthesis both in industry and research. However, the link between the control voltage and the resultant current is often complicated and easily misinterpreted. To overcome this fundamental problem, we propose an optical spectro-electrochemistry instrument based on a two-dimensional CCD detection array. This radically new approach enables simultaneous spectroscopic and spatial data mapping in the realm adjacent to an electrode surface. Important applications range from unequivocal identification of elusive molecules to monitoring metal corrosion. Our first objective is to elucidate certain crucial transformations of mono- and binuclear heavy metal complexes.Read moreRead less
