BODIPY functional metal–organic-frameworks for efficient visible-light-driven water oxidation without additional photosensitizers

Abstract

A novel photosensitizer-catalyst assembly (BODIPY-MIL-88B (Fe)) has been successfully fabricated via one-step solvothermal method and successfully employed as a light-driven water oxidation catalyst. Compared with the conventional multicomponent system, BODIPY-MIL-88B...

Diiodo-BODIPY Sensitizing of the [Mo3S13]2– Cluster for Noble-Metal-Free Visible-Light-Driven Hydrogen Evolution within a Polyampholytic Matrix

“…Zhao and co-workers made use of the easily accessible triplet state for triplet–triplet annihilation, , reaching triplet state lifetimes up to 66.3 μs. Additionally, BODIPY-based dyes have been applied in dye-sensitized solar cells (DSSCs) − with a donor–BODIPY–acceptor architecture as well as in artificial photosynthetic systems toward photocatalytic hydrogen evolution. − …”

Covalent Linkage of BODIPY‐Photosensitizers to Anderson‐Type Polyoxometalates Using CLICK Chemistry

“…This is due to the versatile photophysical properties, high chemical stability, as well as easy and versatile chemical modification of BODIPY [30,31] . Consequently, BODIPY derivatives have been employed in light‐driven hydrogen evolution, [32] CO 2 reduction, [33] and water oxidation [34] …”

“…[30,31] Consequently, BODIPY derivatives have been employed in light-driven hydrogen evolution, [32] CO 2 reduction, [33] and water oxidation. [34] Taking inspiration from these studies, we here report a CLICK-chemistry based system which enables the covalent linkage of an azide-functionalized Anderson type polyoxometalate 1 with two alkyne-functionalized BODIPY 2 to give a covalent BODIPY-Anderson-dyad 3. This concept is based on earlier studies by Oms, Dessapt, Mialane and co-workers, who demonstrated that CLICK-chemistry can be used to access these types of dyads.…”

Design of BODIPY functional ZIF-90 towards enhanced visible-light driven antibacterial performance

“…48 BODIPY-ZIF-90 and ZIF-90 exhibit an intense absorption at about 300 nm, which is assigned to the ligand-to-metal charge transfer (LMCT) of the imidazole nitrogen to zinc. 49 The differences of the UV-vis spectra of BODIPY-ZIF-90 and ZIF-90 indicate the successful introduction of the BODIPY group in ZIF-90, which can broaden the optical absorption and improve the photosensitivity of BODIPY-ZIF-90. At the same time, the aggregation of BODIPY is easily inhibited due to the porous structure of ZIF-90.…”
