Novel visible-light-responsive BODIPY-based MOFs exhibited excellent photocatalytic activity toward oxidation of sulfides and arylboronic acids under ambient conditions, which was attributed to the active oxygen species produced in reaction.

Abstract Modifying redox potential of substrates and intermediates to balance pairs steps are important stages for multistep photosynthesis but faced marked challenges. Through co‐clathration iridium photosensitizer imine substrate within one packet a metal‐organic capsule shift the potentials substrate, herein, we reported multiphoton enzymatic strategy generation heterocycles by intramolecular C−X hydrogen evolution cross‐couplings. The cage facilitated pre‐equilibrium substrate‐involving clathrate that cathodic shifts oxidation substrate‐dye‐host ternary complex configuration inversion via spatial constraints in confined space. new two photon excitation enabled precise control electron transfer between each pair (photosensitizer, capsule), endowing catalytic system proceeding smoothly with an fashion. Three kinds 2‐subsituted (−OH, −NH 2 , −SH) imines N‐aryl enamines all give corresponding cyclization products efficiently under visible light irradiation, demonstrating promising microenvironment driven thermodynamic activation host‐dye‐substrate synergistic combination photocatalytic transformations.

Natural copper oxygenases provide fundamental principles for catalytic oxidation with kinetically inert molecular oxygen, but it remains a marked challenge to mimic both their structure and function in an entity. Inspired by the CuA enzymatic sites, herein we report two new photoactive binuclear copper–iodine- bisbenzimidazole-comodified coordination polymers reproduce natural oxo-functionalization repertoire unique photocatalytic pathway. Under light irradiation, Cu–halide effectively reduce NHP esters complete oxygen reduction activation via photoinduced electron transfer aerobic oxidative coupling of hydroquinone terminal alkynes, affording hydroxyl-functionalized ketones high efficiency selectivity. This supramolecular approach developing bioinspired artificial that merge transition metal- photocatalysis supplies way fabricate distinctive photocatalysts desirable performances controllable precise active sites.

Enzymes facilitate chemical conversions through the integrated activity of multicomponents, but aggregation multiactive sites with molecular containers to emulate enzymatic conversion remains challenging. Herein, we report a new CeIII-based octahedral cage chloride ligands that boosts C(sp3)−H photoactivation by marrying CeIV–Cl photocatalyst and photoredox catalyst integrate photoinduced electron transfer (PET), ligand-to-metal charge (LMCT), hydrogen-atom (HAT) events multiphoton excitation. This binds 2-chloro-9H-thioxanthen-9-one (TXO) for boosting PET via pseudointramolecular pathway oxidize CeIII–Cl form TXO•–. The LMCT excitation is triggered Cl• activates HAT, resulting in regeneration formation an alkyl radical. TXO•– reduces reaction intermediate, which transforms facilitates recovery TXO subsequent recycling. approach offers feasible strategy creating highly electrophilic radicals resembling enzymes demonstrates their potential functionalization.
