    Structural Diversity of Zirconium Metal–Organic Frameworks and Effect on Adsorption of Toxic Chemicals
    摘要:
    While linkers with various conformations pose challenges in the design and prediction of metal-organic framework (MOF) structures, they ultimately provide great opportunities for the discovery of novel structures thereby enriching structural diversity. Tetratopic carboxylate linkers, for example, have been widely used in the formation of Zr-based MOFs due to the ability to target diverse topologies, providing a promising platform to explore their mechanisms of formation. However, it remains a challenge to control the resulting structures when considering the complex assembly of linkers with unpredicted conformations and diverse Zr6 node connectivities. Herein, we systematically explore how solvents and modulators employed during synthesis influence the resulting topologies of Zr-MOFs, choosing H4TCPB-Br2 (1,4-dibromo-2,3,5,6-tetrakis(4-carboxyphenyl)benzene) as a representative tetratopic carboxylate linker. By modulating the reaction conditions, the conformations of the linker and the connectivities of the Zr6 node can be simultaneously tuned, resulting in four types of structures: a new topology (NU-500), she (NU-600), scu (NU-906), and csq (NU-1008). Importantly, we have synthesized the first 5-connected Zr6 node to date with the (4,4,4,5)-connected framework, NU-500. We subsequently performed detailed structural analyses to uncover the relationship between the structures and topologies of these MOFs and demonstrated the crucial role that the flexible linker played to access varied structures by different degrees of linker deformation. Due to a variety of pore structures ranging from micropores to hierarchical micropores and mesopores, the resulting MOFs show drastically different behaviors for the adsorption of n-hexane and dynamic adsorption of 2-chloroethyl ethyl sulfide (CEES) under dry and humid conditions.

    could control photophysics, in particular, cycloreversion kinetics, with a level of control that is not accessible in the solid state or solution. On the series of photoactive materials, we demonstrated for the first time that photoisomerization rates of photochromic compounds could be tuned within almost 2 orders of magnitude. Moreover, cycloreversion rates of photoresponsive derivatives could be modulated
    刺激响应材料对于解决先进技术领域的新兴需求以及当前的工业挑战至关重要。在这里,我们首次报告了在金属有机骨架 (MOF) 刚性支架内具有光致变色螺吡喃和二芳基乙烯部分的光响应构建块的协调集成可以控制光物理,特别是环回复动力学,其控制水平为在固态或溶液中无法获得。在一系列光敏材料上,我们首次证明了光致变色化合物的光异构化速率可以在近 2 个数量级内进行调整。此外,光响应衍生物的循环回复率可以作为框架结构的函数进行调节。此外,通过 MOF 工程,我们能够实现配位固定的螺吡喃衍生物的完全异构化,通常在固态下表现出有限的光开关行为。例如,光谱分析表明,接枝到 MOF 支柱主链上的新型单取代螺吡喃衍生物表现出显着的光异构化速率 0.16 s-1,这是溶液中环回复的典型特征。我们还将获得的基本原理应用于材料特性变化的映射,这可以为监测材料老化或结构退化提供途径。光谱分析表明,接枝到 MOF 支柱主链上的

Herein, a series of isostructural MOFs (M-NU-1008), with M being hexanuclear clusters of transition metals (Zr and Hf), a lanthanide (Ce), or an actinide (Th), were successfully synthesized and evaluated as Lewis acid catalysts, and CO2 cycloaddition of styrene oxide was used
    金属有机骨架(MOF)已作为路易斯酸性催化剂用于多种反应的广泛研究。但是,催化中的MOF节点的身份和性质仍然不确定。本文成功合成了一系列同构MOF(M-NU-1008),其中M为过渡金属(Zr和Hf),镧系元素(Ce)或an系元素(Th)的六核簇,并被评估为路易斯酸催化剂,并使用环氧乙烷的CO 2环加成作为测试反应。用Ce-NU-1008观察到的催化活性优于其他基于M 6的MOF。除了四种M-NU-1008中金属之间的路易斯酸度不同在可变温度扩散反射红外傅里叶变换光谱研究的支持下,在暴露路易斯酸性金属位点之前,发现M 6簇中末端水分子的解离在MOF之间有所不同。在容易发生水从金属结点解离的MOF中,其催化活性高于在其中结合水更牢固的MOF中。经进一步研究,发现与部分制备的催化剂相比,部分除去了末端水的Hf-NU-1008-dehy表现出增强的活性。

    Here we developed a facile solvent-assisted ligand exchange method for synthesizing thioether-containing hybrid metal–organic frameworks (MOFs) that cannot be made using direct synthesis. Such a tailored approach provides an alternative method to achieve thioether-based MOFs and its oxidation-decorated materials. These materials showed the ability to take up heavy metals from solution and the ability

In this study, a phase transition from a microporous MOF, scu-NU-906, to a mesoporous MOF, csq-NU-1008, was discovered and monitored through in situ variable temperature liquid-cell transmission electron microscopy (VT-LCTEM), high-resolution transmission electron microscopy (HRTEM) and in situ variable temperature powder X-ray diffraction

    isostructural series of Np(V) MOFs with shp-topology were synthesized and characterized. X-ray diffraction data revealed an unusual wheel-shaped node of eighteen neptunyl polyhedra stabilized in the framework. Strong distortion in local coordination of the neptunium atoms is evidenced by Np-Oyl bond lengths that lie outside the typical range for Np(V). The structure was further interrogated by Raman spec-troscopy
