Donor-acceptor engineering of a triplet-exciton-optimized MOF photocatalyst for efficient singlet oxygen-mediated oxidation.

ABSTRACT: The exploration of photocatalysts (PCs) for efficient singlet oxygen (¹O₂)-based photocatalytic oxidation is critical and challenging. Herein, a new series of donor-acceptor metal-organic frameworks (D-A MOFs) are constructed through the engineering of the D-A system, and investigated as PCs for the ¹O₂ oxidation reaction. By regulating the intersystem crossing and reversed intersystem crossing features of the D-A system, D-A MOFs could reveal highly tunable triplet-exciton generation. Via the synergy of the enhanced electron transfer properties and the effective energy transfer to ground-state O₂, the optimized D-A MOF (C1) could reveal remarkable activity toward ¹O₂ generation under appropriate irradiatio
