Special Issue Information

Dear Colleagues,

This Special Issue is devoted to Metal-Organic Frameworks (MOFs), which, during the last three decades, have been an emerging and very vibrant field in modern materials design and synthesis. The combination of classical coordination chemistry and porosity has resulted in unique and intriguing properties of this class of materials. This group of materials with programable porosity has revolutionised our understanding of interface properties, including host–guest interactions, and shifted many borderlines in the design of solid state systems. Currently MOF-5, HKUST-1, ZIF-8, UiO-66, and MIL-101 are often regarded as scientific benchmarks and versatile platforms capturing enormous research efforts for various applications.

Gas storage and the separation of gases and vapors belong to pioneering applications in this field; however, interest in porous coordination polymers has quickly diverged in many directions including catalysis, sensing, drug delivery, energy capture, and transformation, among others. Apart from synthetic efforts, many research groups have been involved in better understanding studied systems from a computational perspective. More recent developments in the field are directed towards a combination of porous coordination polymers with other groups of materials with different properties. This combination at the interface of two different materials should result in the development of new composite systems that will combine properties of both components. Seeking new potential applications is of major importance in the MOF field.

The aim of current Special Issue is to cover various aspects connected with the design, synthesis, modification, characterisation, and applications of various groups of MOFs and their composites with other materials. Apart from broadly studied potential applications, we would like to encourage demonstration of less common applications of MOF-based systems, e.g., in food, agriculture, or environmental treatment systems. It is our pleasure to invite you to submit manuscripts for this Special Issue, including communications, full papers, and reviews.

Abstract
New Ag(I) coordination polymers, formulated as [Ag(µ-PTAH)(NO3)2]n (1) and [Ag(µ-PTA)(NO2)]n (2), were self-assembled as light- and air-stable microcrystalline solids and fully characterized by NMR and IR spectroscopy, [...] Read more.
New Ag(I) coordination polymers, formulated as [Ag(µ-PTAH)(NO3)2]n (1) and [Ag(µ-PTA)(NO2)]n (2), were self-assembled as light- and air-stable microcrystalline solids and fully characterized by NMR and IR spectroscopy, electrospray ionization mass spectrometry (ESI-MS(±), elemental analysis, powder (PXRD) and single-crystal X-ray diffraction. Their crystal structures reveal resembling 1D metal-ligand chains that are driven by the 1,3,5-triaza-7-phospaadamantane (PTA) linkers and supported by terminal nitrate or nitrite ligands; these chains were classified within a 2C1 topological type. Additionally, the structure of 1 features a 1D→2D network extension through intermolecular hydrogen bonds, forming a two-dimensional hydrogen-bonded network with fes topology. Furthermore, both products 1 and 2 exhibit remarkable antimicrobial activity against different human pathogen bacteria (S. aureus, E. coli, and P. aeruginosa) and yeast (C. albicans), which is significantly superior to the activity of silver(I) nitrate as a reference topical antimicrobial.

Porous metal-organic framework (MOF) materials UiO-66(Zr) obtained by solvothermal and microwave advanced synthesis (MWAS) procedures were characterized, and their catalytic efficiency was investigated for oxidative desulfurization (ODS) processes using a multicomponent model diesel containing benzothiophene and dibenzothiophene derivatives. The preparation parameters as the cooling time after oven use in the solvothermal procedure, and also the reaction time in the MWAS method seemed to play an important role in the catalytic performance of the UiO-66(Zr) material, as well as in its recycle capacity. The material prepared by the solvothermal procedure with a fast cooling time showed the best catalytic performance (desulfurization efficiency of 99.5% after 3 h). However, the application of the UiO-66(Zr) material prepared by the MWAS method (desulfurization efficiency of 96% after 3 h) conciliated a higher number of advantages, such as shorter reaction time preparation (15 min) and high catalytic activity for a higher number of reaction cycles. The UiO-66(Zr) prepared by the MWAS method was used for the first time in an oxidative desulfurization process, and according to the catalytic results obtained (high recycle capacity and stability) and shorter reaction time preparation, seems to be a promising material for industrial application.

A series of imine-based covalent organic frameworks decorated in their cavities with different alkynyl, pyrrolidine, and N-methylpyrrolidine functional groups have been synthetized. These materials exhibit catalytic activity in aqueous media for the hydrolytic detoxification of nerve agents, as exemplified with nerve gas simulant diisopropylfluorophosphate (DIFP). These preliminary results suggest imine-based covalent organic frameworks (COFs) as promising materials for detoxification of highly toxic molecules. Full article

A series of titanium-based, metal–organic framework (MOF) materials, xM@NH2-MIL125(Ti) (x is the alkali metal loading percentage during the synthesis; M = Li, Na, K), have been synthesized solvothermally. Alkali metal doping in the NH2–MIL125(Ti) in situ solvothermal process demonstrated a vital modification of the material structure and surface morphology for the CO2 adsorption capacity at ambient conditions. By changing the reactants’ precursor, including different kinds of alkali metal, the morphology of xM@NH2–MIL125(Ti) can be adjusted from a tetragonal plate through a circular plate to a truncated octahedron. The variation of the alkali metal loading results in substantial differences in the CO2 adsorption. The properties of xM@NH2–MIL125(Ti) were evaluated via functional group coordination using FT-IR, phase identification based on X-ray diffraction (XRD), surface morphology through scanning electron microscopy (SEM), as well as N2 and CO2 adsorption by physical gas adsorption analysis. This work reveals a new pathway to the modification of MOF materials for high-efficiency CO2 adsorption. Full article
