Selenoxanthylyl radicals – characterization and conPET catalysis

Year: 2026

Type: article

Abstract: Selenoxanthylium photocatalysts are designed based on their ground-state properties to enable low-energy photon photocatalysis, although reductive quenching of their excited state generates persistent selenoxanthylyl radicals. Herein, we report the characterization of selenoxanthylyl radicals by EPR, cyclic voltammetry, UV-Vis spectroscopy, and TD-DFT calculations, together with their application in consecutive photoinduced electron-transfer (conPET) catalysis.
