Summary: Medi-MOF-1 is a porous Metal-Organic framework (MOF) made of Zn(II) and curcumin. The crystal obtained was characterized using powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM). A micrometer-sized crystal with similar morphology was successfully obtained using the solvothermal method. Thanks to its high surface area, stability, and abundant pores, the as-synthesized Medi-MOF-1 can be used to adsorb various gases (H-2, CO2, CH4, and N-2) and iodine (I-2). The activated sample showed a high I-2 adsorption ability of 1.936 g g(-1) at room temperature through vapor diffusion. Additionally, the adsorbed I-2 could be released slowly in ethanol, indicating its potential application for iodine adsorption.

Summary: Pursuing top-performing materials with excellent structural stability and regeneration for effective adsorption of tetrafluoromethane (CF4) from the CF4/N2 mixture is important. A highly stable Ni-MOF, named Ni(ADC)(DABCO)0.5 with anthracene rings-functionalized ultramicroporous chemistry, was prepared to separate the gaseous CF4/N2 blend. It showed excellent CF4 adsorption capacity (0.52 mmol g-1) and selectivity (23.0) exceeding most reported materials, solving the trade-off issue between CF4/N2 separation selectivity and CF4 uptake.

Summary: The adsorptive separation of ethane/ethylene mixtures has attracted great attention due to its potential in reducing energy consumption in the petrochemical industry. However, constructing ethane-selective adsorbents is challenging. In this study, a perylene diimide-based zirconium metal-organic framework (Zr-Me-PDI) was developed for efficient separation of ethane from ethylene. The Zr-Me-PDI exhibited superior stability and showed ethane-selective adsorption behavior. This research provides valuable guidance for the design and synthesis of ethane-selective adsorbents.

Summary: A multi-stage core-expansion method is proposed to optimize acetylene uptake and selectivity in porous materials. The strategy is demonstrated through the synthesis of eight cationic pore-partitioned materials and the optimized structure shows the highest C2H2 uptake capacity and C2H2/CO2 selectivity. This breakthrough in C2H2 capacity and selectivity makes the material among the best for C2H2 uptake and separation.

Summary: The design of MOFs with high connectivity ligands is an important approach for enhanced stability materials and high dimensionality networks. A new class of tetra-isophthalate hyper-carboxylate ligands containing flexible, linear diamine cores has been reported. These ligands, when combined with copper(ii) paddlewheel SBUs, form MOFs with cage-type cavities that increase in size with longer diamine cores. However, the flexibility of the ligands also leads to the formation of concomitant products.
