Photoredox Catalysis Using Heterogenized Iridium Complexes** [PDF]
Chemistry – A European Journal, 2021 Abstract Heterogenized photoredox catalysts provide a path for sustainable chemical synthesis using highly tunable, reusable constructs. Here, heterogenized iridium complexes as photoredox catalysts were assembled via covalent attachment to metal oxide surfaces (ITO, ZrO 2 ,

Asymmetric counteranion-directed photoredox catalysis
Science, 2023 Photoredox catalysis enables distinctive and broadly applicable chemical reactions, but controlling their selectivity has proven to be difficult. The pursuit of enantioselectivity is a particularly daunting challenge, arguably because of the high energy of the activated radical (ion) intermediates, and previous approaches have invariably required ...
