Article Abstract
Two distinct Cd metal-organic frameworks (MOFs) with the formulas {[Cd(BBZB)(oba)]·HO} (JXUST-45) and {[Cd(BBZB)(bpdc)]·2HO} (JXUST-46) featuring 2D layer and 3D pillar-layer structures, respectively, have been prepared, which were regulated by aromatic dicarboxylate ligands (4,4'-diphenyl ether dicarboxylic acid, Hoba; 4,4'-biphenyldicarboxylic acid, Hbpdc; and 4,7-bis(1-benzimidazol-1-yl)-2,1,3-benzothiazole, BBZB). JXUST-45 and JXUST-46 can be considered good fluorescence sensors toward Al, Fe, AcO, CrO, and L-serine. Meanwhile, JXUST-45 and JXUST-46 have good thermal stability and recovery ability. In addition, JXUST-45- and JXUST-46-based fluorescent test papers and light-emitting diode lamps have been further developed to realize naked-eye detection of Al, Fe, AcO, CrO, and L-serine, which has great potential for practical applications.

In contrast to metal ions that have been routinely used to construct metal-organic frameworks (MOFs), anions have rarely been used as essential coordination centers in supramolecular organic frameworks (SOFs). In this work, we present a SOF, , based on the coordination of chloride anions and a flexible oligopyrrole. Owing to the multiple interactions between individual oligopyrrole molecules and an A-B-C-style stacking of the 2D honeycomb layers, crystalline exhibits reasonable thermal stability and retains its structure upon desolvation.

The development of high-performance, cost-effective non-noble metal catalysts for the oxygen evolution reaction (OER) is critical to advancing sustainable hydrogen production via water electrolysis. Herein, we report a facile and mild strategy for synthesizing amorphous bimetallic organic framework materials (NiFe-MOFs) using pyridine-modified threonine (l-PyThr) as an organic ligand. The optimized NiFe-PyThr-4:1 catalyst exhibits remarkable OER activity, requiring low overpotentials of only 162 and 222 mV to achieve current densities of 10 and 100 mA cm, respectively, along with a small Tafel slope of 34.

Metal-organic frameworks (MOFs) are distinguished by their structural diversity, tunable electronic properties, and exceptional performance in various applications. Notably, the electron-donating ability of ligands significantly enhances the ligand-to-metal charge transfer (LMCT) processes within these frameworks, thereby promoting efficient charge migration. Herein, we developed two electron-rich macrocyclic ligands derived from phenothiazine- and phenoxazine-functionalized calix[3]arenes, alongside their corresponding cobalt-coordinated MOFs.

Diabetic infected wounds represent a formidable clinical challenge characterized by persistent hyperglycemia-induced pathological cascades that disrupt normal healing processes through multiple mechanisms including chronic inflammation, oxidative stress, and microvascular dysfunction. As prototypical chronic wounds, they exhibit severely impaired tissue regeneration due to this multifaceted dysfunction in both skin architecture and biological function. Metal-organic frameworks (MOFs) have emerged as promising next-generation therapeutic platforms owing to their exceptional structural tunability, multifunctional properties, and precise spatiotemporal drug delivery capabilities.

The application of nanoscale metal-organic frameworks (MOFs) in tissue engineering is receiving increased attention. As three-dimensional scaffolding materials that provide an appropriate extracellular microenvironment supporting the survival, proliferation, and organization of cells play a key role tissue engineering, hybridization of nanoscale MOFs with bulk hydrogels has led to the development of nanoscale MOF-combined hydrogels. However, development of nanoscale MOF-combined hydrogel scaffolds remains challenging.
