A new porous metal-organic framework (MOF) with the chemical formula [YL(OH)(DMF)]·5HO (1) (where L = 3-amino-4-hydroxybenzoate) has been prepared by a solvothermal procedure. The structural characterization reveals that this material consists of a robust three-dimensional metal-organic framework (MOF) grown with clusters formed by Y(iii) and hydroxide anions joined to one another by the ligand, giving rise to an open structure with interconnected microchannels with variable dimensions. This assembled set has shown to possess a fascinating catalytic activity for the cyanosilylation of a broad range of aldehydes and ketones with exceptional recyclability, a solvent-free medium, and one order of magnitude lower catalyst loading compared to all related lanthanide-based MOFs described so far in the literature.

In recent years, photosensitizer-based phototherapy has gained increasing attention in antibacterial applications due to its low cost, noninvasive nature, and low drug resistance. Among various materials, porphyrin-based metal-organic frameworks (MOFs) have demonstrated great potential, due to their good biocompatibility, facile designability, and excellent light absorption capabilities that enable highly efficient antibacterial efficacy. However, further optimization of their antibacterial performance remains a key challenge.

Recently, metal-organic frameworks (MOFs) have shown high potential in the field of sensing. However, fluorescent-based detection with MOFs in solution needs complex pre-treatments and has stability issues, complicating measurements and handling for sensing applications. Here, an easy-to-handle and low-cost strategy is introduced to convert MOF-based sensing from solution to surface using scanning probe lithography.

Flexible metal-organic frameworks (MOFs) have emerged as a new generation of porous materials and are considered for various applications such as sensing, water or gas capture, and water purification. MIL-88 A (Fe) is one of the earliest and most researched flexible MOFs, but to date, there is a lack in the structural aspects that govern its dynamic behaviour. Here, we report the first crystal structure of DMF-solvated MIL-88 A and investigate the impact of real structure effects on the dynamic behaviour of MIL-88 A (Fe), particularly upon water adsorption.

High-concentration electrolytes (HCEs) face inherent challenges such as high viscosity and diminished ionic conductivity caused by the formation of three-dimensional (3D) anion networks, which limit their practical applications. In this study, it is demonstrated that encapsulating HCEs within metal-organic frameworks (MOFs) effectively disrupts these 3-D networks, resulting in significantly enhanced ionic conductivity. Raman spectroscopy, nuclear magnetic resonance (NMR), and molecular dynamics (MD) simulations reveal a significant reduction in aggregates (AGGs)-state anion within MOF-confined electrolytes, confirming the reconstruction of the solvation environment.
