Recent Advances in Heterogenization of Photocatalysts on Polymer Supports and Applications in Organic Synthesis
Résumé
The photocatalysis is a powerful tool in organic synthesis to generate reactive intermediates and create challenging chemical bonds. The reactivity on such process is mainly controlled by a photocatalyst (PCat) which is designed to ensure both selectivity and efficiency. In the pursuit of more economical and environmentally friendly approaches, the heterogenization of photocatalysts has become increasingly essential, and it is still challenging. Among the various insoluble supports studied, polymers offer several appealing characteristics, such as stability, ease of synthesis, porosity, and recyclability. This review aims to summarize the recent progress in heterogenization of photocatalyst on polymer including the polymerization of PCat, post‐grafting of PCat and 3D‐printing. For the selected heterogeneous photocatalyst, examples of organic transformations and evidence of photocatalytic efficiency will be discussed.
