Indium based metal organic framework crystals (AUBM-1) were successfully synthesized via a solvothermal synthesis process. SXRD analysis showed the production of a new In-MOF structure with a pts topology. AUBM-1 was shown to be chemically stable and was used as an adsorbent to efficiently remove arsenic from water.

Metal organic framework (MOF) is a recent class of porous materials that are built from metal cluster and organic linker. Among the discovered MOFs, UiO-66 has demonstrated both attributes of water stability and hydrophilic, making it suitable for wastewater treatment. In this study, 0.5 wt% UiO-66 was integrated into polysulfone membrane as nanofiller to form mixed-matrix membrane (MMM) with a thin-film composite, dense polyamide layer formed on top of the substrate layer that intended to remove 100 ppm of arsenic V from wastewater through forward osmosis. The successful synthetization of UiO-66 nanoparticle was proven by XRD and FESEM. The pure water permeability was significantly higher with the presence of LiCl in dope solution as pore former. It was found that the arsenic rejection achieved was 87.5% with satisfactory water flux and salt reverse flux.

<b>Materials that combine magnetic order with other desirable physical attributes offer to revolutionize our energy landscape. Indeed, such materials could find transformative applications in spintronics, quantum sensing, low-density magnets, and gas separations. As a result, efforts to design multifunctional magnetic materials have recently moved beyond traditional solid-state materials to metal–organic solids. Among these, metal–organic frameworks in particular bear structures that offer intrinsic porosity, vast chemical and structural programmability, and tunability of electronic properties. Nevertheless, magnetic order within metal–organic frameworks has generally been limited to low temperatures, owing largely to challenges in creating strong magnetic exchange in extended metal–organic solids. Here, we employ the phenomenon of itinerant ferromagnetism to realize magnetic ordering at <i>T</i><sub>C</sub> = 225 K in a mixed-valence chromium(II/III) triazolate compound, representing the highest ferromagnetic ordering temperature yet observed in a metal–organic framework. The itinerant ferromagnetism is shown to proceed via a double-exchange mechanism, the first such observation in any metal–organic material. Critically, this mechanism results in variable-temperature conductivity with barrierless charge transport below <i>T</i><sub>C</sub> and a large negative magnetoresistance of 23% at 5 K. These observations suggest applications for double-exchange-based coordination solids in the emergent fields of magnetoelectrics and spintronics. Taken together, the insights gleaned from these results are expected to provide a blueprint for the design and synthesis of porous materials with synergistic high-temperature magnetic and charge transport properties. </b>

A simple solvent- and catalyst-free method is presented for the synthesis of the mesoporous metal-organic framework (MOF) MAF-6 (RHO-Zn(eIm)2) based on the reaction of ZnO with 2-ethylimidazole vapor at temperatures ≤ 100 °C. By translating this method to a chemical vapor deposition (CVD) protocol, mesoporous crystalline films could be deposited for the first time entirely from the vapor phase. A combination of PALS and Kr physisorption measurements confirmed the porosity of these MOF-CVD films and the size of the MAF-6 supercages (diam. ~2 nm), in close agreement with powder data and calculations. MAF-6 powders and films were further characterized by XRD, TGA, SEM, FTIR, PDF and EXAFS. The exceptional uptake capacity of the mesoporous MAF-6 in comparison to the microporous ZIF-8 is demonstrated by vapor-phase loading of a molecule larger than the ZIF-8 windows.
