Article Abstract
Two [Ru(bpy)] derivative-incorporated polyoxometalate-based metal-organic frameworks (POM@MOFs), {Cd(HO)Mn(HO)[Ru(dcbpy)][PMoMoO]}·6HO () and {Cd(HO)Cu(HO)[Ru(dcbpy)][PMoMoO]}·6HO (), have been prepared through a conventional hydrothermal method. The introduction of Ru metalloligands enhanced the visible light absorption of POM@MOFs, and the photocatalytic detoxification reaction of mustard gas simulant 2-chloroethyl ethyl sulfide (CEES) confirmed their fascinating photocatalytic performances. Under visible light irradiation (λ > 400 nm), both and exhibited efficient photocatalytic properties for the detoxification of CEES into nontoxic CEESO in air, with a selectivity of 97% and a TOF of 26.6 min. Besides, also exhibited commendable reusability and stability after three reaction cycles. In addition, EPR measurements and radical scavenging experiments were carried out to verify the generation of O and O, presenting reliable evidence for the detoxification mechanism.

The selective oxidation of benzylic C-H bonds to C═O bonds is an economical strategy to produce aromatic ketones and aldehydes directly. However, the activation of C-H bonds is challenging due to their high bond energy. In this work, two isostructural three-dimensional (3D) Wells-Dawson-type polyoxometalate (POM)-based metal-organic complexes (POMOCs), [Cu(L)(PMoO)(HO)]·16HO () and [Cu(L)(PWO)(HO)]·14HO () (L = ,'-(ethane-1,2-diyl)bis(pyrazine-2-carboxamide)) were synthesized through the self-assembly of Wells-Dawson-type POMs with Cu and a flexible dipyrazine-dicarboxamide ligand L under hydrothermal conditions, which were structurally characterized by infrared spectroscopy (IR) and powder X-ray diffraction (PXRD).

The critical role of chirality in biological and chemical systems has driven the demand for advanced nanocatalytic platforms capable of achieving efficient chiral selective recognition and conversion. The present study details the design of chiral polyoxometalate metal-organic frameworks (POMOFs) based on polyoxometalates, which mimic enzyme-catalyzed multiphase catalysis by combining the redox activity of Keggin-type polyoxometalates with the stereoselectivity of chiral MOFs. This design strategy precludes the aggregation of catalytic sites through uniformly dispersed POM clusters.

Proton exchange membranes are crucial components in electrochemical energy devices. Nevertheless, the development of high-performance proton-conducting materials remains a considerable challenge, primarily due to the inherent difficulty in constructing dense and continuous hydrogen-bonding networks under ambient conditions. To overcome this limitation, the intentional incorporation of short hydrogen bonds has been applied as a critical design strategy and plays a critical role in enabling efficient proton transport.

Crystalline 2D polyoxometalate-based metal-organic frameworks (PMOFs) provide platforms for discussing structure-property relationships. However, properties regulated by releasing guest molecules in 2D PMOFs have rarely been reported. Herein, we fabricated two 2D PMOFs, [TBA][-HPMoMoOZn(BTC)(IM)]·IM (, TBA = tetrabutylammonium ion, HBTC = 1,3,5-benzenetricarboxylic acid, IM = imidazole) and [TBA][-HPMoMoOZn(BTC)(BPE)] (, BPE = 1,2-bis(4-pyridyl) ethylene), where the interlayer regions were occupied by large-sized TBA guests and dangled IM/BPE ligands.
