A new approach to the generation of long-lived charge-separated states in rigid Donor-Bridge-Acceptor systems. Electron transfer and energy transfer are ubiquitous in nature and they provide the key to the design of energy transducing materials. Considerable effort is being expended into studying light-induced electron transfer which leads to the formation of a charge-separated state or molecular "battery". To be useful, these batteries should have lifetimes at least in the microsecond domain ....A new approach to the generation of long-lived charge-separated states in rigid Donor-Bridge-Acceptor systems. Electron transfer and energy transfer are ubiquitous in nature and they provide the key to the design of energy transducing materials. Considerable effort is being expended into studying light-induced electron transfer which leads to the formation of a charge-separated state or molecular "battery". To be useful, these batteries should have lifetimes at least in the microsecond domain and this is not easily achieved in practice. This project will explore a new, elegant, and promising approach to the efficient generation of very long-lived charge-separated states in rigid systems, which is based on triplet sensitisation.

Coinage metal nanoclusters: synthesis, structure and reactivity. Metal catalysts play important roles in the multi-billion dollar production of many industrial and fine chemicals used in wide-ranging applications including pharmaceuticals, insecticides and polymers. Despite the importance of metal catalysed reactions, the molecular details of such processes remain poorly understood. Breakthrough studies highlight that reactions previously thought to be catalysed by discrete metal catalysts are i ....Coinage metal nanoclusters: synthesis, structure and reactivity. Metal catalysts play important roles in the multi-billion dollar production of many industrial and fine chemicals used in wide-ranging applications including pharmaceuticals, insecticides and polymers. Despite the importance of metal catalysed reactions, the molecular details of such processes remain poorly understood. Breakthrough studies highlight that reactions previously thought to be catalysed by discrete metal catalysts are in fact catalysed by metal nanoclusters. This project involves the application of advanced mass spectrometric and computational methods to explore the formation and reactivity of copper, silver and gold nanoclusters. Identification of key reactive intermediates will inform the design of next generation catalysts.Read moreRead less
