Visible-light-driven organic transformations on semiconductors

Along with the increasing interest in exploring green and sustainable approaches in organic synthesis, photon, the cleanest energy form, has been widely utilized in driving various organic transformations. In contrast to well-established organic photocatalysis utilizing homogeneous photosensitizers and photo-catalysts, solid-state semiconductors have received less but rapidly growing interest in this field. Herein, we summarize recent development in organic photocatalysis utilizing semiconductor-based photocatalysts, including metal oxides, metal chalcogenides, and metal-free carbon nitrides. For each category of semiconductors, both oxidation and reduction organic reactions are introduced first, followed by redox coupled reactions utilizing both excited electrons and holes. At the end, the remaining challenges and future opportunities of this field are discussed. (C) 2020 Elsevier Ltd. All rights
