Red light mediated energy transfer catalysis via stable organic radicals

Year: 2026

Type: article

Abstract: Dexter-type doublet-to-triplet energy transfer. We show that TTM-3PCz promotes a broad range of reactions, including photooxidation, cyclization, [2 + 2] cycloaddition, and isomerization. Its performance is on par with traditional rare-metal containing photocatalysts excited with high-energy light. We demonstrate stable organic radicals as a powerful new class of air-tolerant, rare-metal-free photocatalysts for red light mediated transformations.
