To date, numerous materials, including various quantum dots and dyes, have been widely used for the ultrasensitive detection of toxic metal ions as security inks to hide information. Nevertheless, because poor dispersibility solid-state based on such materials scarcely reported. Herein, a highly dispersible water-stable metal–organic framework (MOF; NH2-MIL-125(Ti)) is an invisible ink data coding, encryption, decryption via its "turn-on/off" switching by treatment with...
Water can easily be contaminated by many dye molecules because of its high solubility with dense color. Dye‐contaminated water requires purification via the adsorptive removal molecules, employing various porous materials. To increase efficiency and selectivity, demands for developing new metal–organic frameworks (MOFs) continue to increase. Herein, we present a study on dye‐adsorption properties MOFs based their structures pore sizes. The effects molecule charge size were also investigated....
Abstract The technological developments of metal–organic framework (MOF) for selective adsorption and sensing have been achieved in recent years. Herein, we report two stilbene‐based MOFs, denoted as Zn 3 (SDC) (bpy) ( 1 ) Zn(SDC)(bpy)·2DMF 2 ). MOFs were synthesized pure form by controlling the organic linker ratio used adsorptive removal dye molecules. Despite their low capacities, more toward cationic (methylene blue) than anionic (methyl orange). unique fluorescent property was harnessed...
The development of heterogeneous catalysts for tandem reactions remains a significant challenge practical applications, primarily due to the need multiple isolated catalytic sites. This study presents novel metal‐organic framework (MOF), Cu‐AIPA, formulated as Cu(AIPA)(DMF)2 (AIPA: 2‐amino isophthalic acid, DMF: N, N‐dimethylformamide). Cu‐AIPA integrates three distinct mechanisms: redox activity, Brønsted basicity, and Lewis acidity. structure features redox‐active Cu(II) centers basic...

The synthesized ligand M(II) (M = Cu, Zn, Cd) characterized to confirm their purity successful synthesis using H NMR, 13 C FTIR spectroscopy. Thermal analysis demonstrated stability, whereas UV‐Vis spectroscopy molar conductance studies provided insights into electronic properties coordination behavior....
A new homocyclic methylbenzyl naphthalene (MBN) compound has been developed as a novel liquid organic hydrogen carrier (LOHC) medium with high gravimetric storage capacity of 6.44 wt % and good dehydrogenation ability. According to the results theoretical calculations designed MBN, MBN media possesses one lowest enthalpies (<56 kJ molH2–1) among LOHC media. The Friedel–Craft alkylation reaction allows formation an regioisomeric mixture, which minimizes production cost for practical...
Abstract Zr‐based metal–organic frameworks (MOFs) were modified with pendant tetrazole ligands for proton conductivity studies. Although tetrazolate coordinated to metal cations have been widely utilized construct MOFs or porous coordination polymers, date, the use of uncoordinated groups in has limited. In this study, a benzene‐1,4‐dicarboxylic acid (BDC‐N 4 ) was synthesized and used prepare UiO‐66 MOF using mixed‐ligand strategy. The tetrazole‐functionalized UiO‐66‐N compared containing...

Abstract Green fuel from water splitting is hardcore for future generations, and the limited source of fresh (<1%) a bottleneck. Seawater cannot be used directly as feedstock in current electrolyzer techniques. Until now single atom catalysts were reported by many synthetic strategies using notorious chemicals harsh conditions. A cobalt single‐atom (CoSA) intruding oxide ultrasmall nanoparticle (Co 3 O 4 USNP)‐intercalated porous carbon (PC) (CoSA‐Co @PC) electrocatalyst was synthesized...
Collective information on the electrocatalytic activity, selectivity, durability, and reaction mechanisms of pristine MOF-based catalysts for reactions such as ORR, OER, HER, CO 2 RR is presented.
Porosity control and structural analysis of metal–organic frameworks (MOFs) can be achieved using regioisomeric ligand mixtures. While ortho-dimethoxy-functionalized MOFs yielded highly porous structures para-dimethoxy-functionalized displayed almost nonporous properties in their N2 isotherms after evacuation, ligand-mixed showed variable uptake amount surface area depending on the ligand-mixing ratio. The quantity absorbed was tuned between 20 300 cm3/g by adjusting Both experimental...
