Amide compounds are widely present in drug molecules and natural products, which can be synthesized by acid-amine condensation. It is urgent to design new photocatalysts for achieving both nitroaromatic reduction and C-H oxidation to obtain raw materials, carboxylic acids, and aromatic amines. Herein, a novel isopolymolybdate-incorporated photoactive metal-organic framework, -TPT, was constructed by combining the oxidation catalyst [MoO], Ni(II) cation, and photosensitive ligand 2,4,6-tri(4-pyridyl)-1,3,5-triazine (TPT).

Directed synthesis of high-efficiency visible photoinduced Baeyer-Villiger oxidation catalysts is of primary significance. Here, the isopolymolybdate anion [β-MoO] is for the first time encapsulated with the photosensitive metalloligand [Ru(bpy)(Hdcbpy)] (bpy = 2,2'-bipyridine; Hdcbpy = 2,2'-bipyridine-5,5'-dicarboxylic acid) to synthesize polyoxometalate@metal-organic frameworks, {(CdDMF)[Ru(bpy)(dcbpy)]([β-MoO])}·5DMF (Ru-Mo). The composite photocatalyst Ru-Mo not only has a light absorption of 700 nm but also shortens the photogenerated electron transfer distances and accelerates charge and proton transfer.

We present a nonclassical {Ru(CH)}-containing isopolymolybdate CsKNaH{[(CH)Ru]MoO}·35HO () via one-pot reaction. The crystallographic characterization of compound revealed that it contains an unusual {MoO} cluster together with six {Ru(CH)} groups, having the largest number of {Ru(CH)} groups within the field of {Ru(CH)}-containing polyoxometalates. Results showed that compound displayed excellent proton conductivity (9.

The combination of electron-deficient viologen ligands with electron-rich POMs is a typical acceptor-donor system that has recently received much attention. Under solvothermal and hydrothermal conditions, by introducing three symmetric viologen ligands into POM-based hybrid materials, we successfully constructed four POMs-viologen inorganic-organic hybrid compounds, namely (1,3-bcbpy)·(δ-MoO) (1) (1,3-bcbpy·2Cl = 1,1'-bis(3-carboxybenzyl)-4,4'-bipyridine dichloride), {Co(1,4-bcbpy)(HO)[H(β-MoO)]}·2HO·2CHO (2), (1,4-bcbpy)·(δ-MoO)·2HO (3) (1,4-bcbpy·2Cl = 1,1'-bis(4-carboxybenzyl)-4,4'-bipyridine dichloride, CHO = formaldehyde), and {Cu(1,1-pmbby)(HO)[H(β-MoO)]}·5HO·CHN (4) (1,1-pmbby·2Cl = 1,1'-[1,4-phenylbis(methylene)]bis-(4,4'-bipyridine)dichloride, CHN = dimethylamine). These four compounds exhibit different fascinating structures, especially compound 4 is a typical metal-organic framework.

Organic solar cell (OSC) has drawn considerable interest in recent decades owing to their advantages of light weight, flexible, large area and potentially low-cost. Employing an appropriate hole-transporting layer (HTL) into an OSC device has been proved as an efficient method to obtain high efficiency OSC due to the enhancement of the hole transporting and extraction of the device. In this work, aqueous solution-processed MoO(s-MoO) thin films were employed as HTLs to construct non-fullerene PM6:Y6 OSCs.
