Summary: Metal-organic framework (MOF) materials show remarkable performance in gas separation, but it is challenging to obtain materials with high gas capacity and selectivity simultaneously. In this study, MOF-801-(Zr/Ce/Hf) was created based on the green synthesis of the MOF-801 construction unit, and the impact of three metal nodes on gas adsorption and separation performance was demonstrated. The results showed that MOF-801-(Ce) had the best CO2 adsorption capacity and excellent separation performance in CO2/CH4 and CO2/N-2 systems.

Summary: A new 2D flexible cobalt(ii) framework (Co-MOF) undergoes reversible structural transformation upon guest molecule removal/uptake. After activation, Co-MOF-alpha with 1D porous channels transforms into Co-MOF-beta (0D voids) with changes in metal and carboxylate coordination modes, rotation of organic linkers, and contraction of interstitial spaces. Gas adsorption experiments reveal that Co-MOF-beta exhibits a two-step CO2 adsorption isotherm and close-to-open isotherms for C2H2, C2H4, and C2H6 at 195 K, demonstrating selective uptake of C2H2 over CH4 and CO2 at room temperature.

Summary: A new C2H2 adsorption trap (UPC-80) constructed by 4-fold interpenetration nets is reported, which shows high adsorption selectivities of 6.34 and 4.78 for C2H2/CO2 and C2H2/C2H4, respectively. Laboratory-scale fixed-bed breakthrough experiments confirm the efficient separation ability of UPC-80 towards the C2H2/CO2 and C2H2/C2H4 gas mixtures, with negligible capacity loss. Theoretical simulations attribute the good separation performance to the anchoring of C2H2 by two Tb2(COO)6 clusters in adjacent interpenetration nets and the strong electrostatic interaction.

Summary: One of the major challenges in photocatalytic CO2 reduction is achieving control over the selective formation of a single product while maintaining a high conversion efficiency. In this study, a conjugated microporous polymer (TEB-BPY) was synthesized and characterized, and it was found that Re@TEB-BPY exhibited high photocatalytic activity for CO2 reduction to CO or CH4. The presence of triethylamine (TEA) or 1-benzyl-1,4-dihydronicotinamide (BNAH) as sacrificial electron donors influenced the selectivity of the products.

Summary: Porous, supramolecular structures can selectively encapsulate guest molecules by exploiting differences in noncovalent interactions. The encapsulation preferences are influenced by the geometry and chemical nature of the guest molecules. Designing a host with chemical specificity requires an accessible and complementary recognition site. However, in the case of a supramolecular, porous coordination polymer (PCP), the selectivity for a haloaromatic isomer is not only based on geometry and shape, but also on the chemical nature of the guest, without relying on a complementary recognition site.
