Summary: Efficient capture and selective separation of CO2 is achieved using stable Al-based MOFs with multiple adsorption sites, as demonstrated by MOF-303(Al) with high CO2 capacity and recyclability. Moreover, MOF-303(Al) exhibits excellent selective separation performance for CO2 from CO2/CH4 and CO2/N2 mixtures, making it a potential material for natural gas purification. The multiple adsorption sites (mu-OH, N-H, N-N, and C-H) contribute to the superior CO2 adsorption and selective separation performance of MOF-303(Al), with the mu-OH and N-H sites playing a more significant role.

Summary: In recent years, light-responsive molecules have been incorporated in metal-organic frameworks (MOFs) to fabricate light-responsive intelligent devices, where reversible isomerization of the guest molecules in the nanopores is crucial. However, how to design a porous environment of MOFs to achieve a reversible isomerization remains unknown until now. In this work, donor-acceptor Stenhouse adducts (DASAs), a new kind of visible light responsive compound, were confined in the nanopores of different MOFs to study their isomerization upon visible-light irradiation/mild heating. We found that the polarity of the pore environment is the key to control the reversibility of isomerization of such guest molecules. Under the guidance of this principle, MIL-53(Al) was screened to investigate the proton conductivity and switching performance of the DASA-confined MOF. The proton conductance was up to 0.013 S cm(-1) at 80 degrees C and 98 % RH, and at least 30 switching cycles were achieved thanks to the Grotthuss-type mechanism and the low polarity of MIL-53(Al) pore environment.

Summary: In this work, two bodipy-based MOFs, BMOF 1D and BMOF 2D, were assembled using dicarboxyl-functionalized bodipy ligands. The conversion of BMOF 1D to BMOF 2D and the spontaneous exfoliation process resulted in the formation of nanometer-thick BMOF 2D and one layer MOF nanosheets (BMON 2D). Both BMOF 2D and BMON 2D exhibited high reactivity and recyclability in photocatalytic reactions to produce α-amino organoborons and α-amino amides.

Summary: In this study, an amino-modified ZIF-90 was designed and prepared, and these ZIFs could reversibly transfer between organic solvents and water by alternate bubbling of CO2 and N-2 through adjusting the hydrophobicity and hydrophilicity of surface species. The phase transfer mechanism was found to be caused by the reversible formation of hydrophilic salts upon CO2 addition. By utilizing this property, an efficient and regulable CuI-catalyzed cycloaddition was achieved using the amino-modified ZIF-90 for encapsulating, activating, and reusing the catalyst, and regulating the reaction.

Summary: In this study, a new type of thermally responsive material was fabricated by anchoring polyethylene glycol functionalized ionic liquids (ILs) on the walls of covalent organic frameworks (COFs) through strong hydrogen bonding. The ILs exhibited lower critical solution temperature (LCST)-type phase behavior within the COF nanopores under high moisture levels, similar to traditional IL/water mixtures. The strong interaction between the IL and COF led to a decrease in the phase separation temperature of the aqueous IL within the COF channels. The proton conductivity of ILm @COF could be reversibly switched by phase miscibility and separation in the COF nanopores, with no obvious decrease observed even after 20 switching cycles.

Summary: Selective intramolecular dehydration of biomass-derived cyclic alcohols to cyclic alkenes is achieved via cation- and anion-confined catalysis over Lewis acid imidazolium-Zn based ionic liquids. The [BMIm][Zn2Cl5] catalyst provides a confined microenvironment for the coordination of Zn2+ with hydroxyl O of cyclic alcohols, leading to exclusive intramolecular dehydration.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
