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.
