One major theme of research in the Yoon Lab is the development of unique chemical transformations enabled by visible light photochemistry. A variety of transition metal photocatalysts responsive to visible light are known, and the Yoon Lab has shown that their well understood photochemistry can be coupled to cycloadditions, arene oxidations, amine functionalizations, and thiol-ene reactions, among others. An important feature of this strategy is the ability to use rational ligand modifications to tune the photophysical and electrochemical properties of the catalyst, exemplified by the complexes below.
