Organophotocatalysis Using Red to Near-Infrared Light

Abstract

Over recent years, photocatalysis has progressed substantially with the utilization of red to near-infrared (NIR) light to drive chemical transformations. Nevertheless, metal-based complexes continue to dominate this spectral region, despite their high cost and potential toxicity, which restrict their application in large-scale processes and biological settings. The development of efficient metal-free organic photocatalysts capable of operating under red and NIR light therefore represents a compelling research direction. This review surveys recent advances in red- and NIR-light-promoted reactions enabled by metal-free organic photocatalysts.
