Summary: Incorporating functionality into MOFs has attracted interest due to the tunability of their properties. Ligand functionalization of MOF-74 is challenging, but this study successfully achieved defect generation and ligand functionalization using fragmented organic ligands. The resulting defect-engineered Ni-MOF-74 derivatives maintained good crystallinity and exhibited modified porosity and CO2 adsorption properties.

Summary: Augmented reality (AR) is an emerging technique that enhances visualization and understanding of complex 3D materials. It has applications in various fields such as chemistry, real estate, physics, and mechanical engineering. In this study, we demonstrate a workflow for an app-free AR technique that enables visualization of metal-organic frameworks (MOFs) and other porous materials to study their crystal structures, topology, and gas adsorption sites. This workflow can be a valuable tool for computational and experimental scientists in their research and educational endeavors.

Summary: Understanding the mechanism of MOF crystal growth is crucial for their design. In this study, Deng and colleagues employ an optical method to visualize and track the crystal interface during MOF growth. They also derive a reaction kinetic equation for individual crystals of MOFs, which offers valuable guidance for MOF synthesis.

Summary: Zr-MOF was synthesized using zirconium acetate and 2,5-dihydroxyterephthalic acid as metal ion and organic ligand, respectively. Characterization of Zr-MOF was performed by SEM, XRD, and TG. It exhibited higher adsorption capacity for norfloxacin removal from aqueous solution compared to another adsorbent. The optimal conditions for maximum adsorption capacity of 134.5 mg/g after 5 h were found at pH 10. This study highlights the potential of Zr-MOF for efficient and cost-effective purification of aqueous solutions.

Summary: Tailoring reaction kinetics is crucial in designer electrocatalysts for selectively converting atmospheric species into useful products. This study demonstrates a supportive effect in tuning the electrocatalytic kinetics of oxygen reduction reaction by attaching metalloporphyrin-based MOFs crystals onto graphene support, leading to highly selective peroxide production. The discovery of a magic angle for co-facial alignment optimization reveals the importance of maximizing pi-pi interaction for mitigating lattice and symmetry mismatch between MOF and graphene, ultimately facilitating electron migration and oxygen chemisorption.

Summary: Three new zirconium chelidamates, including a complex, a porous metal-containing hydrogen-bonded network (M-HOF), and a metal-organic framework (MOF), were synthesized and characterized. The structures were determined using various techniques and the sorption properties were investigated. These compounds exhibit high structural flexibility and stability in organic solvents. The M-HOF shows high selectivity towards water, while the MOF exhibits porosity towards multiple adsorbates.

Summary: In this study, a fluorescent organosilica coating was successfully added to ZIF-8 nanomaterial to enhance bio-interaction and prevent material flocculation. The results showed that the modified ZIF-8@BPMO nanomaterials had high adsorption capacity for curcumin, following a pseudosecond-order kinetic model and the Freundlich model. Therefore, the fluorescent ZIF-8@BPMO nanoparticle holds great potential for bio-applications.

Summary: The emission of sulfur dioxide from flue gases is harmful to human health and the environment. Developing new metal organic frameworks to capture this toxic molecule is important in flue gas desulfurization. The newly synthesized MOF, ECUT-Th-60, exhibits higher uptakes of SO2 compared to CO2 and N-2 under the same conditions, making it promising for the separation of SO2 from gas mixtures.
