“…Polyhedron-based metal–organic frameworks (PMOFs) have a large-void cage interconnected through windows of different sizes and open channels, which gives them the opportunity to construct PMOFs with large pore volumes, high surface areas, and excellent selective gas absorption capacities. , Notably, the typical PMOF materials composed of V-type tetracarboxylate linkers and [Cu 2 (COO) 4 ] paddlewheel units have an extraordinary specific surface area. − The CC triple bond within the molecular structure of C 2 H 2 forms a strong interaction with the open metal sites (OMSs) in the PMOFs. Therefore, functionalized O/N sites and OMSs are introduced to enhance the adsorption capacity of C 2 H 2 gas, thereby improving separation efficiency.…”

The separation of acetylene (C 2 H 2 ) from ethylene (C 2 H 4 ) and ethane (C 2 H 6 ) is crucial for the production of high-purity C 2 H 2 and the recovery of other gases. Polyhedron-based metal−organic frameworks (PMOFs) are characterized by their spacious cavities, which facilitate gas trapping, and cage windows with varying sizes that enable gas screening. In this study, we carefully selected a class of PMOFs based on V-type tetracarboxylic acid linker (JLU-Liu22 containing benzene ring, JLU-Liu46 containing urea group and recombinant reconstructed In/Cu CBDA on the basis of JLU-Liu46) to study the relationship between pore environment and C 2 adsorption and separation performance. Among the three compounds, JLU-Liu46 exhibits superior selectivity toward C 2 H 2 /C 2 H 4 (2.06) as well as C 2 H 2 /C 2 H 6 (2.43). Comparative structural analysis reveals that the exceptional adsorbed-C 2 H 2 performance of JLU-Liu46 can be attributed to the synergistic effects arising from coordinatively unsaturated Cu sites combined with an optimal pore environment (matched pore size and polarity, urea functional group), resulting in a strong affinity between the framework and C 2 H 2 molecules. Furthermore, transient breakthrough simulations of JLU-Liu46 confirmed its potential for separating C 2 H 2 in ternary C 2 gas.

“…Compared with traditional porous adsorbent materials, MOFs exhibit great the advantages of excellent stability, a tunable pore size and a large surface area. Therefore, MOFs have attracted significant attention for many applications, such as catalysis, gas adsorption, magnetism, membrane separation, photonic, sensors and so on [15][16][17][18][19][20][21][22][23][24]. Owing to their large surface area, large pore volume and facile functionalization, MOFs are very suitable for use as biocompatible and biodegradable drug carriers, exhibiting great application potential in the field of drug delivery.…”

Metal–organic frameworks (MOFs) are considered to be promising materials for drug delivery. In this work, a Zinc-based MOF nanocomposite IRMOF-3 was introduced as a drug carrier for 10-hydroxycamptothecine (HCPT). Without an extra drug-loading process, a nanoscale drug delivery material HCPT@IRMOF-3 was prepared via one-pot synthesis. The composition and structure of the material were investigated, and the drug release character was measured. Compared with preparing IRMOF-3 first and loading the drug, the one-pot-prepared HCPT@IRMOF-3 exhibited a higher drug-loading capacity. The material presented pH-responsive release. The HCPT release rate at pH 5.0 was significantly higher than that at pH 7.4. The cytotoxicity experiments showed that IRMOF-3 was non-toxic, and HCPT@IRMOF-3 exhibited notable cytotoxicity to Hela and SH-SY5Y cells. One-pot synthesis is a simple and rapid method for the preparation of an MOF drug delivery system, and IRMOF-3 can be potentially used in pH-responsive drug delivery systems.
