Across the Board: Yang Li on Visible-Light Photoredox Catalysis

In this series of articles, the board members of ChemSusChem discuss recent research articles that they consider of exceptional quality and importance for sustainability. This entry features Prof. Y. Li, who discusses visible-light photoredox catalysis by acridinium photocatalysts, which show both powerful oxidative and reductive abilities. She also highlights the mechanism for generation of a neutral acridine radical and its application in the reduction of aryl halides.
