Séminaire d’Oliver S. Wenger en MODE HYBRIDE
This first half of this talk will concentrate on the application of transient UV-Vis absorption spectroscopy to elucidate photoredox mechanisms, with particular focus on the usefulness of triplet-triplet annihilation upconversion for challenging reduction reactions. By combining the energy input from two photons, a variety of reductive dehalogenation and detosylation reactions requiring very negative reduction potentials become achievable using long-wavelength irradiation instead of UV light.
The second half of the talk will focus on recent advances in the development of precious metal-based sensitizers for triplet energy transfer catalysis, and on the development of new luminophores and photocatalysts based on first-row transition metals. This will include conceptually new types of coordination compounds made from manganese, cobalt, and chromium, which complement the well-known photophysical and photochemical properties of traditional ruthenium- or iridium-based complexes.
