“…In addition, the solid‐state 13 C NMR of terephthalic acid as solid has been also measured, and the result is presented in the Supporting Information as Figure SI8. Peaks at 130, 132 and 173 ppm in terephthalic acid were assigned to carbons in the aromatic ring and the carbonyl groups, respectively . Analogous peaks can be observed from pristine UiO66 Zr at 127, 136 and 169 ppm in accordance with the literature (Figure ) .…”

Prolonged (weeks) UV/Vis irradiation under Ar of , UiO66 Zr-NO 2 ,M IL101 Fe,M IL125 Ti-NH 2 , MIL101 Cr and MIL101 Cr(Pt) shows that these MOFs undergo photodecarboxylation of benzenedicarboxylate (BDC) linker in as ignificant percentage depending on the structure and composition of the material. Routine characterization techniques such as XRD,U V/Vis spectroscopya nd TGA fail to detect changes in the material, although porosity and surface area change upon irradiation of powders.I n contrast to BCD-containing MOFs,zeolitic imidazolate ZIF-8 does not evolve CO 2 or any other gas upon irradiation.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under https://doi.

“…An alternative strategy was employed for the installation of ethanolamine onto the Zr 6 clusters of UiO‐66, by exposing dehydrated UiO‐66 (UiO‐66 heated at 300 °C for 1 hour under an N 2 atmosphere) to an anhydrous toluene solution containing ethanolamine (ea) . Similar to UiO‐66‐ox, UiO‐66‐ea [Zr 6 O 4 (OH) 2 (ea) 2 (bdc) 6 ] n contains pendant amino moieties (ethanolamine is grafted onto Zr 6 clusters at the triangular windows formed between three Zr IV ions, partially replacing bridging µ 3 ‐OH moieties) which were expected to improve the material's CO 2 adsorption capacity.…”

Metal-organic frameworks (MOFs) have been in the spotlight for a number of years due to their chemical and topological versatility. As MOF research has progressed, highly functionalised materials have become desirable for specific applications, and in many cases the limitations of direct synthesis have been realised. This has resulted in the search for alternative synthetic routes, with postsynthetic modification (PSM), a term used to collectively describe the functionalisation of pre-synthesised MOFs whilst maintaining their desired characteristics, becoming a topic of interest. Advances in the scope of reactions performed are reported regularly; however reactions requiring

“…[152,153,214] In MOFs containing open metal sites, guest molecules are often bound to these and variation in the 2 H, 13 C or 17 O anisotropic NMR parameters with temperature can be used to determine the type and rate of restricted motion occurring, giving information on the binding strength and mode. [215][216][217][218][219] One of the systems studied in most detail to date is CO 2 adsorbed in Mg-CPO-27 (Mg 2 (dobdc), dobdc = 2,5-dioxobenzene-1,4-dicarboxylate). Kong et al [215] used the CSA of 13 CO 2 to investigate this binding, showing that the CO 2 molecule rotated about the Mg-O bond axis at an angle, θ, which varied from 69° at 210 K to 56° at 375 K, as shown in Figure 21(b).…”

Although the solid state is typically characterised by inherent periodicity, many interesting physical and chemical properties of solids arise from a variation in this, i.e., changes in the nature of the atom occupying a particular site in a crystal structure or variation in the position of an atom (or group of atoms) in different parts of a structure, or variation as a function of time. This lack of long-range order poses significant challenges, not just for the characterisation of the structure of disordered materials, but also simply for its description. The sensitivity of nuclear magnetic resonance (NMR) spectroscopy to the local, atomic-scale environment, without the requirement for long-range order, makes it a powerful tool for the study of disorder in the solid state. Information on the number and type(s) of coordinating atoms or through-space and through-bond connectivity between atomic species enables the construction of a detailed picture of the structure. After a brief description of the background theory of NMR spectroscopy, and the experimental methods employed, we will describe the effects of disorder on NMR spectra and the use of calculations to help interpret experimental measurements. We will then review a range of applications to different types of disordered materials, including oxides and ceramics, minerals, porous materials, biomaterials, energy materials, pharmaceuticals, polymers and glasses. We will discuss the most successful approaches for studying different materials, and illustrate the type of information available and the structural insight gained.
