New materials for sensitized photo-oxygenation
Résumé
A variety of photosensitizers has been included, adsorbed or grafted onto different supports. This review focuses on original new materials designed for photoinduced oxygenation reactions, using light as the activation method and oxygen as the reactant. Such materials find widespread applications for the oxidation of fine chemicals under mild conditions, for water treatment, for photodynamic bactericidal inactivation or photodynamic therapy. The generation, diffusion and reactivity of Reactive Oxygen Species (ROS), and particularly of singlet oxygen 1O2 in these heterogeneous media are discussed. © The Royal Society of Chemistry 2011.
