Imine-linked donor–acceptor metal–organic frameworks for an efficient photocatalytic oxidative coupling reaction

Abstract

Donor-acceptor metal-organic frameworks (D-A MOFs) are promising platforms for photocatalytic organic transformation and energy conversion due to their controllable chemical structures and tunable energy band gaps. Herein, we report two...

Three-Component Construction of Mesoporous Metal–Organic Frameworks and Their Incorporation into Solid Polymer Electrolytes for Li-Ion Conduction

“…We choose to explore the synthesis of MOFs with linker construction in situ because constructing both coordinative linkages and dynamic covalent linkages allows the formation of new organic linkers with extended length, which would provide mesopores for polymer chains and lithium salts. MOFs based on cyclic trinuclear Cu 3 (PyCA) 3 (HPyCA = 1 H -pyrazole-4-carbaldehyde) are of particular interest to us because they also provide Cu-based interacting sites, and their synthesis based on two kinds of linkages have been successfully demonstrated. − For example, JNM-7 was very recently synthesized from Cu 3 (PyCA) 3 and benzidine (BD), and the newly constructed linker endowed the material with a low band gap for efficient photocatalysis.…”

Novel BODIPY-based MOFs toward high-efficiency photocatalytic oxidation of sulfides and arylboronic acids

“…1–4 Of the reported photocatalysts, well known as porous crystalline materials built through coordination bonds between metal ions (or metal clusters) and organic connectors, metal–organic frameworks (MOFs) have emerged as an ideal photocatalysis platform for diverse organic transformations. 5–19 For the formation of photo-mediated reactive oxygen species (ROS), incorporation of predesignable organic chromophores as bridging ligands to endow MOFs with photoactivity has been demonstrated as an efficient strategy. 20–22 Notably, the integration of well-isolated chromophores into one architecture suppresses the aggregation-caused quenching of photosensitizers.…”
