A Novel Zinc-Based MOF Featuring 2,4,6-Tris-(4-carboxyphenoxy)-1,3,5-triazine: Structure, Adsorption, and Photocatalytic Activity

Crystals, Год журнала: 2025, Номер 15(4), С. 348 - 348

Опубликована: Апрель 8, 2025

A metal–organic framework, MOF-S1, was synthesized via a solvothermal reaction between 2,4,6-tris-(4-carboxyphenoxy)-1,3,5-triazine (TCPT) and zinc nitrate hexahydrate. Single-crystal powder X-ray diffraction analyses confirmed the formation of hexagonal rod-shaped crystals with trigonal (P-31c) structure featuring two-fold interpenetrated 3D framework. comprehensive characterization—including NMR spectroscopy, thermogravimetric analysis, surface area measurements (using Langmuir, t-plot, Horváth–Kawazoe, Dubinin–Radushkevich models)—revealed an ultramicroporous material Langmuir 711 m2/g median pore width ~6.5 Å. Adsorption studies using Congo Red, Methylene Blue, Methyl Orange, Rhodamine B demonstrated rapid uptake effective removal from aqueous solutions, kinetic modeling indicating dominant chemisorption mechanism. Photocatalytic tests under UV irradiation yielded degradation efficiencies ~93% for Orange ~74% B. These findings suggest that MOF-S1 is promising candidate wastewater treatment applications UV-related processes, offering strong adsorption capacity thermal stability.

New Trends in Click Reactions for Synthesis of 1,2,3‐Triazole Derivatives

Chemistry & Biodiversity, Год журнала: 2025, Номер unknown

Опубликована: Май 26, 2025

ABSTRACT Among various heterocyclics, five‐membered triazole nitrogen heterocycles show vast application in the medicinal, industrial, and agricultural sectors, so forth. The Cu‐catalyzed click reaction has gained significant attention from investigators for selective synthesis of derivatives, but toxicity occurs due to excessive presence copper final product associated intake limits its application. In quest development sustainable synthetic strategies, copper‐free, metal‐free, water‐assisted reactions are becoming popular. view this, present review article focuses on recent developments (last 10 years) made afford derivatives high yield, mild conditions, easy isolation purification products readily available starting materials. Besides, novel eco‐friendly such as photocatalytic reactions, metal–organic framework‐based metal‐free solvent‐free electrochemical have been reviewed. addition, patents current clinical trials triazoles discussed.

Abstract The strategy of designing heterogeneous porous catalysts by a post-modification method is smart to increase the catalytic power desired catalysts. Accordingly, in this report, metal-organic frameworks based on titanium with acetic acid pending were designed and synthesized via method. structure target catalyst has been investigated using different techniques such as FT-IR, XRD, SEM, EDX, Mapping, N 2 adsorption/desorption (BET/the BJH) correctness its formation proven. application Ti-based MOFs functionalized was evaluated preparation new spiropyrans, obtained results show that performance improved modification. through methods presents sophisticated approach enhancing efficacy In context, our study focuses synthesis characterization (MOFs) titanium, pendants, Various techniques, including Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive (EDX), mapping, (BET/BJH), employed investigate composition catalyst. These collectively confirmed successful structural integrity products melting point, 1 H-NMR 13 C-NMR FT-IR techniques. Examining general process shows mentioned modification very useful for purposes. presented used wide range biologically active spiropyrans good yields. simultaneous presence several cores will highlight biological properties these compounds. present offers promising insight into rational design, synthesis, task-specific catalysts, particularly context synthesizing candidate molecules.
