Preparation of a porphyrin-polyoxometalate hybrid and its photocatalytic degradation performance for mustard gas simulant 2-chloroethyl ethyl sulfide

The tail of imidazole regulated the assembly of two robust sandwich-type polyoxotungstate-based open frameworks with efficient visible-white-light-driven catalytic oxidation of sulfides

“…Thus, several strategies have been developed to extend their absorption to the visible region by introducing inorganic complex components onto narrow band gap semiconductors, and combining metal-organic complexes or organic conjugated molecules with POMs. 33,34 Based on the above inspirations, the construction of highly active POM-based photocatalysts via the combination of metal-organic units and POMs with MMCT behavior to improve visible-light absorption is required to make the sulfoxide production more efficient and practical.…”

Polyoxometalates Embedded into Covalent Triazine Frameworks Regulating Charge Transfer for Visible-Light-Driven Synthesis of Functionalized Sulfoxides and Detoxification of Mustard Gas Simulants

“…Recently, two strategies have been developed to guide the synthesis of POM-based photocatalysts for visible-light-driven oxidation of sulfides, including decorating transition metal cations to lacunary POMs and coupling photosensitizers with POMs. Yamaguchi’s group regulated the highest occupied molecular orbitals (HOMOs) or lowest unoccupied molecular orbitals (LUMOs) by introduction of Ce or V into lacunary silicotungstate and employed them for the oxidation of sulfides under the irradiation of visible light. , Wang et al prepared H 2 TClPP-H 2 PVMo from organic photosensitizer 5,10,15,20-tetra­(4-chlorine)­phenylporphyrin and Keggin-type H 5 PV 2 Mo 10 O 40 as catalytic activity center, which shows good catalytic activity for visible-light-driven oxidation of 2-chloroethyl ethyl sulfide (CEES) . Lin et al obtained donor–acceptor photocatalysts constructed from the perylene diimide derivatives and POMs for visible-light-induced CEES oxidation .…”

Supramolecular hybrids based on Ru(ii) porphyrin and octahedral Mo(ii) iodide cluster

“…4–8 Indeed, there are many examples of porphyrin-based hybrids with different inorganic substrates, such as magnetic nanoparticles, 9,10 nanocarbons (fullerenes, graphene oxide, and carbon dots), 11–15 quantum dots, 16,17 and polyoxometalates. 18–21 Lately, multicomponent porphyrin hybrid architectures composed of more than two molecular units have become a focus of interest. 22,23 Several strategies have been used to create such supramolecular aggregates, the most common being the formation of metal-directed coordination bonds.…”
