Beyond Closed-Shell Photochemistry: Singlet Oxygen Generation Driven by 10H-Phenothiazine Radical Cation

Abstract Phenothiazines are widely studied as closed-shell photosensitizers; however, their open-shell oxidized forms remain largely unexplored in photochemical contexts. Here, we investigate the photophysics and reactivity of the radical cation of 10H-phenothiazine (PHT•+) using...
