Catalysis under irradiation by visible light has become a highly dynamic and promising research area in chemical sciences. Such catalysis primarily entails photoinduced electron- and energy-transfer chemistry sensitized by polypyridyl complexes, organic dyes, and heterogeneous catalysts. Remarkably though, while the electrochemical and photophysical properties of these catalysts have been extensively studied, only recently has the chemical community begun to appreciate the great potential of the utilization of visible-light photocatalysis as a broadly useful methodology to advanced organic syn...
