Photoredox Catalysis for Polymerization Reactions
CHIMIA, 2012 Photoredox catalysis is now well-known in organic synthesis for the formation of free radicals under very soft irradiations conditions (e.g. sunlight, household fluorescence or LED bulbs, Xe lamp).

Organic synthesis using photoredox catalysis [PDF]
Beilstein Journal of Organic Chemistry, 2014 Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research.

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 ...

Cooperative Photoredox Catalysis Under Confinement. [PDF]
ChemistryAbstractPhotoredox catalysis has emerged as a potent means to conduct synthetic chemistry. Leveraging light to achieve challenging organic transformations has led to many developments, both of fundamental and industrial nature. Despite their potency, photoredox processes are inherently diffusion controlled, which can limit their ability to enable both ...
