The present study examines the potential coupling between dipolar dynamics and ionic charge transport in metal‐organic framework (MOF) compounds. MOFs are known for their high porosity and customizable properties. By integrating freely rotating dipolar groups into the ligands, a novel structure, CFA‐25, akin to the known BUT‐2 framework, is synthesized. This facilitated the investigation of local and macroscopic effects, particularly the possible interplay between dipolar units and Cs cations. The research aimed to understand fundamental dipolar dynamics and ionic charge transport, employing Cs ions for their X‐ray diffraction characterizability. Experimental analysis using dielectric spectroscopy, complemented by theoretical simulations, explored questions regarding glassy freezing of re‐orientational dynamics, Cs cation motion within the network, and the influence of dipolar units on transport. Contrary to previous reports, this work finds that Cs transport exhibits substantial barriers, necessitating specialized simulation techniques for accurate characterization. This interdisciplinary approach sheds light on the intricate dynamics of MOFs and offers insights into their potential applications involving ion transport phenomena. [ABSTRACT FROM AUTHOR]

The cubic SBU Ni8X6L6 (X = OH−/H2O, L = ligand) is of great interest due to its stability and potential applications when integrated in MOFs. Here, we investigate by detailed DRIFTS measurements and exchange reactions whether it is found to be neutral in MOFs, as previously assumed in the literature, or whether it can show anionic character, as observed in complexes.

The outbreak of the coronavirus (SARS‐CoV‐2) pandemic, its rapid spread, and its fatal consequences clearly showed mankind the overwhelming power of nature, and the importance of interdisciplinary research to counter it. Herein, it will be pointed out what challenges arise in fighting nanosized viruses, which feature an outstanding ability to alter their structure and properties to adapt to infection processes, and why nanoscience is extremely powerful to address them. To learn from the past and to be best prepared for the future, this review highlights how the incredible potential of nanoscience can be tapped by mimicking natures' viruses for the development of maximally efficient pharmaceuticals, e.g., COVID‐19 vaccines, by designing preventive and protective equipment, e.g., face masks, as well as developing nanosensors for early detection of infections.

Thirteen Ni(II) and Co(II) coordination polymers based on the organic linker 1H,1′H‐4,4′‐bipyrazole (H2BPZ) were synthesized and characterized using single crystal X‐ray diffraction, namely Ni(H2BPZ)(acac)2 (1), Ni(H2BPZ)2(H2O)2 ⋅ (NO3)2 (2), Ni3(H2BPZ)6Cl6 ⋅ (DMSO)4 (3), Ni8(H2BPZ)16Cl16 ⋅ (DMSO)6 (4), Ni(H2BPZ)2(H2O)6 ⋅ (ClO3)2(H2O)3 (5), the isotypic structures Ni(H2BPZ)2(CH3SO3)2 (6) and Co(H2BPZ)2(CH3SO3)2 (7), Co(H2BPZ)2(CF3SO3)2 (8), Ni(H2BPZ)3 ⋅ (CF3SO3)2 (9), Ni(H2BPZ)3 ⋅ (ClO4)2 (10), Co(H2BPZ)3 ⋅ (ClO4)2 (11), Ni(BPZ) ⋅ (DMF)0.65 (12), and Ni(BPZ) (13). In order to study the structural correlations of 1D‐3D, 2D‐3D, and 3D‐3D phase transitions the structures were investigated by means of thermal analysis. In addition, the role of charge‐balancing anions with respect to their coordination strength on structure, framework dimension, and crystal properties is discussed in detail. This work exemplifies the function of anions as structure directing agents and how they, as well as thermal activation, can influence framework topology, dimensionality, and crystal size.

We have synthesized a new Cu amalgam, the Cu-rich phase Cu3Hg. It crystallizes with the Ni3Sn structure type with a hexagonal unit cell (space group P63/mmc , a = 5.408(4) Å, c = 4.390(3) Å) and shows some mixed occupancy of Cu on the Hg site, resulting in a refined composition of Cu3.11Hg0.89. This is the first example of an amalgam with the Ni3Sn structure type where Hg is located mainly on the Sn site. Cu3Hg might be one of the phases constituting dental amalgams and therefore has major relevance, as well as the only Cu amalgam phase described so far, Cu7Hg6 with the γ-brass structure. It occurs as a biphase in our samples. Thermal decomposition of Cu amalgam samples in a dynamic vacuum yields nanostructured copper networks, possibly suitable for catalytic applications.

The amalgamation of different disciplines is at the heart of reticular chemistry and has broadened the boundaries of chemistry by opening up an infinite space of chemical composition, structure, and material properties. Reticular design has enabled the precise prediction of crystalline framework structures, tunability of chemical composition, incorporation of various functionalities onto the framework backbone, and as a consequence, fine-tuning of metal-organic framework (MOF) and covalent organic framework (COF) properties beyond that of any other material class. Leveraging the unique properties of reticular materials has resulted in significant advances from both a fundamental and an applied perspective. Here, we wish to review the milestones in MOF and COF research and give a critical view on progress in their real-world applications. Finally, we briefly discuss the major challenges in the field that need to be addressed to pave the way for industrial applications., (© 2021 Wiley-VCH GmbH.)

At its core, reticular chemistry has translated the precision and expertise of organic and inorganic synthesis to the solid state. While initial excitement over metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) was undoubtedly fueled by their unprecedented porosity and surface areas, the most profound scientific innovation of the field has been the elaboration of design strategies for the synthesis of extended crystalline solids through strong directional bonds. In this contribution we highlight the different classes of reticular materials that have been developed, how these frameworks can be functionalized, and how complexity can be introduced into their backbones. Finally, we show how the structural control over these materials is being extended from the molecular scale to their crystal morphology and shape on the nanoscale, all the way to their shaping on the bulk scale., (© 2021 Wiley-VCH GmbH.)

Reticular materials are of high interest for diverse applications, ranging from catalysis and separation to gas storage and drug delivery. These open, extended frameworks can be tailored to the intended application through crystal-structure design. Implementing these materials in application settings, however, requires structuring beyond their lattices, to interface the functionality at the molecular level effectively with the macroscopic world. To overcome this barrier, efforts in expressing structural control across molecular, nano-, meso-, and bulk regimes is the essential next step. In this Review, we give an overview of recent advances in using self-assembly as well as externally controlled tools to manufacture reticular materials over all the length scales. We predict that major research advances in deploying these two approaches will facilitate the use of reticular materials in addressing major needs of society., (© 2020 The Authors.

Owing to their large ratio of surface area to mass and volume, metal-organic frameworks and porous carbons have revolutionized many applications that rely on chemical and physical interactions at surfaces. However, a major challenge today is to shape these porous materials to translate their enhanced performance from the laboratory into macroscopic real-world applications. In this review, we give a comprehensive overview of how the precise morphology control of metal oxides can be transferred to metal-organic frameworks and porous carbon materials. As such, tailored material structures can be designed in 0D, 1D, 2D, and 3D with considerable implications for applications such as in energy storage, catalysis and nanomedicine. Therefore, we predict that major research advances in morphology control of metal-organic frameworks and porous carbons will facilitate the use of these materials in addressing major needs of the society, especially the grand challenges of energy, health, and environment.
