Abstract

When designing metal–organic frameworks (MOFs), linker design is one of the most important factors in constructing a wide variety of structures. Judicious choice of linker size, geometry, and connectivity can create diverse structures and topologies, which can aid in the quest to design MOFs with both high stability and permanent porosity. Multi-connected linkers have become a focus in the MOF community, as high connectivity can improve stability and tunability of frameworks. In particular, multicarboxylate ligands have been reported extensively in the literature to construct stable MOFs with versatile pore environments, which can be termed as metal-multicarboxylate frameworks (MMCFs). These structures have great application potential in

Abstract

Chiral polymers have aroused great attention in among chiral supramolecular materials based on their features. Herein, for the first time, the synthesis of chiral polymeric composites (CMNPs/1,4-Zbtb &1,3-Zbtb) have been reported with entrapment through three strategies: ultrasonic irradiation, solvothermal, and mechanical stirring. According to the obtained results, it is found that ultrasound-assisted synthesis can be considered as an inexpensive and efficient method than the others, from the point of?view?of energy and time consuming. In this strategy, encapsulation of chiral magnetic nanoparticles (CMNPs) by using tetrazole-based polymers (Zbtbs) happens, in-situly. These chiral sphere-like inorganic-organic polymers can be considered a

Abstract

Porous metal–organic frameworks (MOFs) have always been of interest to scientists in all fields of chemistry since their introduction. Due to their brilliant characteristic features, MOFs have been employed in various applications, especially as heterogeneous catalysts. The composite method is among the most important and practical approaches to optimize the performance of MOFs as a catalyst. Combination of MOFs with selected materials provides many benefits for the newly formed compounds (MOF composites) including the synergistic effect that has a vital role in catalysis applications, and elimination of the obstacles associated with the use of bare MOFs. However, environmental hazards should be considered during the synthesis and process

Abstract

In the present study, Keggin-type phosphomolybdic acid (H3PMo12O40) was encapsulated in a sized-matched Zirconium metal-organic framework (PMo12@UiO-67) to be used as a heterogeneous catalyst for oxidative desulfurization. A proper cage size and narrow window of UiO-67 were exploited to avoid the phosphomolybdic acid leaching to provide a suitable platform for a majority of the sulfur compounds. The prepared composite demonstrated remarkable catalytic activity for ultra-deep oxidative desulfurization of 5 sulfur compounds under mild conditions. 37.50 ppm sulfur remained in the oil after 20 min and no sulfur compounds were detected after 30 min. The trapping experiments indicated no contribution of the radical scavenger to the desulfurizat

Abstract

This study has developed a novel approach to the design of nanocomposites derived from Metal-Organic Frameworks (MOFs) which are capable of absorbing ultraviolet (UV) radiation. In this work, two various nanocomposites namely ZnO/C and ZnO/C-W were obtained at 800 ?C from the TMU-21 in an argon and argon atmosphere saturated with water vapors, respectively. Water was used as a weak oxidizing agent to control the ratios of C to ZnO. This is a facile rout to adjust the properties of the obtained nanocomposites. The structure of these nanocomposites was determined by XRD, SEM, FTIR and elemental mapping analysis. Then, to investigate the optical properties of the obtained nanocomposites, two hybrid films were synthesized using poly (vinyl alco

Abstract

Carbon dioxide (CO2) fixation to generate chemicals and fuels is of high current importance, especially toward finding mild and efficient strategies for catalytic CO2 transformation to value added products. Herein, we report a novel Lewis acid–base bifunctional amine-functionalized dysprosium(III) metal–organic framework [Dy3(data)3?2DMF]?DMF (2,5-data: 2,5-diamino-terephthalate), NH2-TMU-73. This compound was fully characterized and its crystal structure reveals a 3D metal–organic framework (MOF) with micropores and free NH2 groups capable of promoting the chemical fixation of CO2 to cyclic carbonates. NH2-TMU-73 is built from the Dy(III) centers and data2– blocks, which are arranged into an intricate underlying net with a rare typ

Abstract

Atomically precise silver nanoclusters (Ag-NCs) are known as a hot research area owing to their brilliant features and they have attracted an immense amount of research attention over the last year. There is a lack of sufficient understanding about the Ag-NC synthesis mechanisms that result in optimal silver nanoclusters with an appropriate size, shape, and morphology. In addition, the coexisting flexible coordination of silver ions, the argentophilic interactions, and coordination bonds result in a high level of sophistication in the self-assembly process. Furthermore, the expansion of clusters by the organic ligand to form a high dimensional structure could be very interesting and useful for novel applications in particular. In this study

Abstract

A high-nucleus silver nanopolycluster as a new type of silver-based polymer supercapacitor (SSc) by a simple and single-step synthesis process was designed and synthesized. The structural, optical, and electrochemical properties of SSc-2 were determined. This highly stable conductive 3D nanopolycluster shows great cycling stability, large capacity, and high energy density without any modification or doping process and so acts as an excellent SSc (412 F g–1 at 1.5 A g–1). In addition, there was a stable cycling performance (94% capacitance) following 7000 cycles at 3 A g–1 current density. The presence of fluorinated groups, 3D expansion of high-nucleus metallic clusters, and porosity are the advantages of SSc-2 that lead to stability

Abstract

Use of preformed metal-organic polyhedra (MOPs) as supermolecular building blocks (SBBs) for the synthesis of metal-organic frameworks (MOFs) remains underexplored due to lack of robust functionalized MOPs. Herein we report the use of polycarboxylate cuboctahedral Rh-II-MOPs for constructing highly-connected MOFs. Cuboctahedral MOPs were functionalized with carboxylic acid groups on their 12 vertices or 24 edges through coordinative or covalent post-synthetic routes, respectively. We then used each isolated polycarboxylate Rh-II-MOP as 12-c cuboctahedral or 24-c rhombicuboctahedral SBBs that, upon linkage with metallic secondary building units (SBUs), afford bimetallic highly-connected MOFs. The assembly of a pre-synthesized 12-c SBB with

Abstract

In the presence of fossil fuels, several environmental concerns, such as energy shortage, environmental pollution, and global warming may occur in the present century. In this respect, supercapacitors have been introduced as green energy storage systems playing a central role in providing a sustainable human society. In this work, an advanced strategy was initially demonstrated through various synergistic effects to synthesize cobalt(II) metal–organic framework#CoMn2O4 nanocomposites (Co(II)-TMU-63#CoMn2O4 NCPs) having interfaces adapted at tunable chemical nanocomposites for hybrid supercapacitors. The given NCPs showed excellent electrochemical performance at 7 A g−1 current density endowed with a specific capacity of 156 mA h g−1 (

Abstract

Porous materials have been investigated as efficient photochromic platforms for detecting hazardous radiation, while the utilization of hydrogen bonded‐organic frameworks (HOFs) in this field has remained intact. Herein, two HOFs were synthesized through self‐assembly of tetratopic viologen ligand and formic acid (PFC‐25, PFC‐26), as a new class of “all‐organic” radiochromic smart materials, opening a gate for HOFs in this desired field. PFC‐26 is active upon both X‐rays and UV light, while PFC‐25 is only active upon X‐rays. The same building block yet different radiochromic behaviors of PFC‐25 and PFC‐26 allow us to gain a deep mechanistic understanding of the factors that control the detection specificity. Theore

Abstract

Fast and selective recognition of nitro explosives (NEs) is an emerging issue of interest. Among different detection systems, pillared metal-organic frameworks (MOFs) demonstrated high applicability in the detection of NEs. A novel pillar-layered MOF, specifically {[Zn2(2,6-NDC)2(dabco)].7DMF?3H2O} (TMU-14) were synthesized by solvothermal reaction of Zn(II) nitrate hexahydrate, 2,6-naphthalenedicarboxylic acid (2,6-NDC) as the O-donor ligand and 1,4-diazabicyclo[2.2.2]octane (DABCO) as the N-donor ligand. This MOF was characterized through Single Crystal X-ray crystallography. This study demonstrated that TMU-14 with a 3D layered structure and a suitable pore window of 10.933?A˚ was an efficient luminescent sensory material through host-g
