Photoredox catalysis is a rapidly growing research area in the field of organic chemistry that utilizes visible light to drive chemical reactions. This type of catalysis involves the excitation of a photosensitive catalyst by visible light, which in turn initiates a redox reaction. Photoredox catalysis has been widely utilized in the development of new synthetic methodologies and has found applications in various areas such as drug discovery, materials science, and organic synthesis. This field has seen significant advances in recent years, leading to the discovery of novel photoredox catalysts and the development of new strategies for the formation of complex organic molecules.
