Summary: A novel strategy was developed to enhance the barrier protection of polyethylene oxide (PEO)-metal-organic framework (MOF) composite films by incorporating impermeable Laponite RD (LRD) clay platelets. The inclusion of LRD platelets improved the barrier performance of the films against toxic chemical threats while maintaining high water vapor transport rates. This approach establishes a new path for improving selective materials for chemical protection applications.

Summary: High-profile assassination attempts have underscored the need for high-performance and field-deployable nerve agent (NA) sensors. In this study, a novel optical sensor based on Fourier transform spectroscopy and cantilever-enhanced photoacoustic detection was developed for the detection of gaseous NAs. The sensor demonstrated fast multi-species gas sensing with high sensitivity and selectivity in a small sample volume, which is advantageous for field analysis of limited NA samples. Future improvements could be achieved by developing more powerful supercontinuum light sources in the mid-infrared region.

Summary: The study demonstrates the catalytic detoxification of two chemical warfare agent simulants using ZnInS/UiO nanocomposites under simulated solar light. The enhanced detoxification efficiency of ZnInS/UiO is attributed to its photothermal effect and close interfacial contact in heterostructures, improving catalytic activity for nerve agent and mustard gas surrogates. The findings offer new opportunities for photo-assisted enhanced detoxification of CWAs with potential applications in multifunctional catalysts based on metal-organic frameworks.

Summary: This study aims to develop highly efficient bifunctional catalysts for the simultaneous detoxification of nerve agent and blister agent, two of the deadliest chemical warfare agents. By introducing two porphyrin-based ligands (TCPP and PPIX) into two-dimensional ultrathin metal-organic framework materials (MOLs), the catalytic activity of the MOLs for nerve agent and blister agent simulants was investigated. The results showed that TCPP-functionalized MOL exhibited the highest catalytic activity for the degradation of blister agent simulant under solar light.

Summary: Metal-organic frameworks (MOFs) have limitations in the hydrolysis of nerve agents due to the stable bridging configuration between the hydrolyzed products and the MOF nodes. This study presents two copper single atom-modified UiO-66 MOFs, which exhibit similar reactivity to the native MOF under aqueous conditions, suggesting the influence of the copper coordination environment on product inhibition.

Summary: This study developed a scalable and controllable strategy to fabricate UiO-66-NH2 on electrospun polyacrylonitrile nanofibers (UiO-66-NH2 fabrics) to capture and catalyze 2-chloroethyl ethyl sulfide (CEES) effectively for self-detoxification. The obtained UiO-66-NH2 fabrics are capable of specific surface area, porosity, crystallinity, and abundant catalytic active sites, enabling efficient removal of CEES up to 97.7% after 48 h. The nanofibrous fabrics possess air-permeable, washable, flexible, and lightweight features, ensuring promising engineering applications for protective clothing.

Summary: Metal-organic polyhedra (MOPs) are discrete molecules with metal ions/clusters and organic ligands, which exhibit intrinsic and extrinsic porosity. In this study, three zirconium(iv)-based MOPs were used for the degradation of trace concentrations of the nerve agent simulant DMNP. All three MOPs showed rapid degradation of DMNP, with half-lives ranging from 17 to 130 s. The catalytic activity of MOPs is attributed to their periodic packing, creating extrinsic porosity for DMNP to interact with the pore surface and Lewis acids of MOPs, as well as the lability of the Zr-Cp- bond.

Summary: This study investigated the adsorption of three chemical warfare agent simulants on MgO and Ti-doped MgO nanotubes. It was found that DMMP and paraoxon interact with the metal oxide surface through their phosphoryl oxygens, while CEES adsorbs through chlorine and results in bond dissociation. The effect of hydroxylation on nanotube properties was also examined, showing that partial hydroxylation promotes maximal adsorption.

Summary: Luminescent metal-radicals have gained attention for their potential applications in materials science. However, the luminescence of metal-radicals tends to decrease after forming metallo-complexes. This study presents a highly luminescent metallo-supramolecular radical cage (LMRC) constructed from a tritopic terpyridinyl ligand RL with a TTM radical and Zn2+. LMRC shows a remarkable photoluminescence quantum yield and high photostability. Additionally, LMRC exhibits significant magnetoluminescence at high concentrations, indicating negligible spin-spin interactions between radical centers.

Summary: This study reports the self-assembly of a tetra-cationic super aryl-extended calix[4]pyrrole tetra-pyridyl ligand into a water-soluble Pd(ii)-cage featuring two endohedral polar binding sites, which requires specific types of guests for efficient assembly. High conformational selectivity is observed in the inclusion of isomers of alpha, omega-bis-formamides, and the uptake and release mechanism/kinetics of selected polar guests are briefly investigated using pair-wise competition experiments.

Summary: Recently, there has been a growing concern about the presence of chemical warfare agents (CWAs) worldwide. Researchers have been using metal-organic frameworks (MOFs), a porous and stable material, to investigate the detoxification mechanisms of CWAs. This review introduces the progress in the adsorption and degradation of CWAs by MOFs powder materials and discusses the development of MOFs composites as protective equipment. It is expected to provide valuable references for the development of new materials and protective equipment for the detoxification of CWAs.

Summary: In this study, we compared and contrasted the hydrolysis reactions of two different aromatic esters using an octanuclear cubic Co-8 coordination cage as the catalyst. The results showed that exterior-surface catalysis can be effective and potentially general, while cavity-binding of guests can result in negative catalysis.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
