Summary: We demonstrate that the carborane-based metal-organic framework (MOF), mCB-MOF-1, exhibits high adsorptive selectivity for CO2:N2 mixtures. This hydrophobic MOF with open metal sites shows exceptional CO2 adsorption capacity and sustained selectivity values even in extremely humid conditions. A comparison with MOF-74(Ni) highlights the superior performance of mCB-MOF-1 under challenging moisture operation conditions.

Summary: Two C2H6-selective metal-organic framework adsorbents were designed and synthesized for one-step separation of ethane/ethylene under humid conditions. The adsorbents exhibited high stability, surface area, and suitable pore size, and demonstrated excellent C2H6/C2H4 selectivity. The adsorbents have the benchmark performance among all reported adsorbents for the separation of C2H6/C2H4 under humid conditions. Adsorbents described in this work can address major chemical industrial challenges.

Summary: A surface-induced polymer coating method is proposed to design hydrophobic zeolite for capturing VOCs under humid conditions. The synthesized Y zeolite@hypercrosslinked polymer composite (Y@P) demonstrates excellent adsorption capability, especially the toluene adsorption capacity of Y@P-2-80 composite is two times higher than that of Y zeolite. The proposed method provides a promising and universal strategy for effective VOCs capture using zeolites with enhanced hydrophobicity under wet conditions.

Summary: This study investigates the co-adsorption of water and carbon dioxide by a high CO2 affinity ultramicroporous material. It is found that slow water sorption kinetics enable shortened adsorption cycles with retention of approximately 90% of dry CO2 uptake. In situ infrared spectroscopy and ab initio calculations provide insight into the binding sites and sorption mechanisms of CO2 and H2O molecules in the ultramicropore.

Summary: CO2 is the main greenhouse gas, and capturing it from flue gas under humid conditions is challenging but important for carbon neutrality. In this study, a highly efficient CO2 capture performance was achieved by integrating specific functionalities such as unsaturated metal sites and amide functional groups. The MOF Fe-dbai exhibited high CO2 adsorption capacity, CO2/N-2 selectivity, and a preserved working capacity under humid conditions. Molecular simulation revealed that the amide CO- group played a crucial role in improving the interaction between Fe UMS and CO2.

Summary: Superhydrophobic conjugated microporous polymer-coated sponges were synthesized by an in situ Sonogashira coupling reaction. The sponges exhibited high water contact angles and enhanced hydrophobicity and stability with the addition of amino groups. They showed excellent absorption capacity for oils, stable after multiple cycles, and efficient oil-water separation. Furthermore, the sponges demonstrated flame retardancy and promise in the treatment of flammable fuels and organic compounds.

Summary: Isomorphic substitution of metal ions can alter the morphology and lattice parameters of AlPO4-5 crystals, as well as tune their water adsorption behavior. Metal substitution affects the hydrophobicity and adsorption capacity of the materials, with an increase in metal content leading to a shift in the onset of the adsorption inflection point. Among the adsorbents tested, an Fe-based AlPO4-5 showed the highest absorption capacity.

Summary: In this study, a robust ultramicroporous metal-organic framework (MET-Fe) is proposed for separating 1-butene isomers through molecular exclusion. The pore aperture size of MET-Fe precisely matches the kinetic diameters of the isomers, as confirmed by static and kinetic adsorption experiments and theoretical calculations. Dynamic breakthrough experiments further demonstrate the excellent separation performance, easy regeneration, and remarkable reusability of MET-Fe under both dry and humid conditions.

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.
