Structure engineering is of great importance to enhance the carrier separation efficiency multiphoton absorption (MPA) materials for near-infrared (NIR) light-driven reactive oxygen species (ROS) generation. In this study, MPA-responsive potassium/cyano group-functionalized graphitic carbon nitride was investigated, demonstrating charge redistribution and improved by density functional theory calculations experimental results. With various types boosted ROS generation under UV-vis or NIR-II light irradiation, could achieve efficient photodynamic therapy after reducing particle size. This study developed a simple strategy manipulate distribution booting NIR light-activated in therapy.

Abstract Enzymatic reductions catalyzed by reductases, such as aldo/ketoreductases (AKRs), imine and ene reductases generally depend on the regeneration of nicotinamide cofactors for industrial viability. This usually involves addition a cosubstrate second enzyme, dehydrogenase, e.g. glucose / dehydrogenase. For commercial viability it would be more interesting to use water sacrificial supply necessary hydrogen atoms. is possible using photocatalytic methods involving precious metal, Rh Ru, complexes electron mediators. A problem associated with photobiocatalysis in general weak penetration ultraviolet or visible light biological systems. Here we report unprecedented near infrared (NIR) combination hybrid photoenzyme based IR responsive reductive graphene quantum dots (rGQDs) that are non-toxic AKRs. We envisaged immobilization AKR close proximity rGQDs could enable direct transfer atoms from prochiral ketone substrate without requiring cofactor. To test this hypothesis, immobilized surface cross-linked AKR. The resulting rGQD/AKR photobiocatalyst mediated synthesis pharmaceutical intermediate, (R)-1-[3,5-bis(trifluoromethyl)-phenyl] ethanol ((R)-3,5-BTPE) corresponding ketone, 82% yield > 99.99% ee under 50 mW·cm− 2 illumination. work opens new avenues create artificial photoenzymes simplify in vitro biocatalysis coupling renewable solar energy sustainable chemical production. Since accounts about half entire spectrum its efficient utilization crucial applications sunlight. have demonstrated our can effectively utilize catalyze enzymatic reduction ketone. these photobiocatalysts insoluble solids they readily recovered, recycled potentially employed continuous flow operation.
