|meso-Met h y l BODIPY photocages stand out for their absorption properties and easy chromophore derivatization. However, their low uncaging efficiencies often hinder applications requiring release of protected substrates in high amounts. In this study, we demonstrate that the sulfonothioated BODIPY group photocleaves a sulfonylthio group from the meso-met h y l position with a 10-fold higher quantum yield than the most efficient leaving groups studied to date. Photocleavage, observed in solution and in cells, is accompanied by the spatiotemporally controlled photo-release of H2Sn. For this reason, sulfonothioated BODIPY may be applied in cell signaling, redox homeostasis, and metabolic regulation studies.
