“…FT-IR spectroscopy is the most appropriate technique to provide ample details to find out how to bind ligands to metal ions. The FT-IR spectrum of CUF-1 (Figure S3) shows a disappearance of the sharp absorption peak at 2924 cm –1 for the NH + group because of the destroying the Zwitter ion effect of the (COO – ) group attached by the Cu metal, which further leads to the disappearance of an absorption peak at 1660 cm –1 for ν(CO) of the carboxylate (COO – ) group and the appearance of a sharp absorption peak at 617 cm –1 owing to the Cu–O bond. , The two sharp absorption peaks at 1501 and 1380 cm –1 for ν(COO – ) asymmetric and symmetric, respectively, indicate the presence of H 2 L in the CUF-1 structure. , The absence of the 1660–1800 cm –1 characteristic bands assigned to the protonated carboxylic groups suggests that the ligand (H 2 L) was fully deprotonated. , The appearance of a sharp absorption peak at 755 cm –1 is attributed to the Cu–O bond of coordinated water, which has been supported by the occurrence of an additional broad band at 3400–3550 cm –1 of the coordinated water . Finally, the disappearance of sharp absorption peaks at 3089 and 1759 cm –1 attributed to ν(NH) and ν(CO) of the ring form (Figure , structure D), respectively, indicates that the ligand (H 2 L) reacted with the Cu(II) ion in the tautomeric form (Figure , structure C).…”

“…At a wavelength of 1.54 Å, the PXRD patterns of H 2 L have been obtained in the range 5–50° (θ). Figure B shows the PXRD pattern of the synthesized Schiff base by the interface process, which belonged to the Pbca (61) space group and has a monoclinic system of pure synthesized H 2 L. The major sharp peaks illustrate that H 2 L has been extremely crystalline on the nanometric scale (derived from the Debye–Scherrer equation) …”

Metal−organic frameworks (MOFs) are attractive materials to be used as ionophores because of the array of nurturing features for instance a significant surface area, a porous structure, and also electrocatalytic activity. Aluminum is an important metal regarding its many applications such as in industry, biology, medicine, and so forth, so its estimation in very low levels is a challenging mission. Herein, a carbon paste electrode has been developed based on a novel prepared Cu-MOF with a nano-Schiff base linker. The prepared ionophore was characterized using many analytical and spectroscopic methods. The X-ray diffraction data suggested that the newly synthesized Cu-MOF has a mesoporous structure. For Al(III) determination in different real water and pharmaceutical samples, the established electrode has been successfully used with high precision (RSD% = 0.82−1.98) and accuracy (recovery % = 98.0−101.2) and showed good agreement with the atomic absorption spectroscopy results. The sensor under study exhibited Nernstian behavior toward the Al(III) ion (19.89 ± 0.63 mV decade −1 ) wrapping a large linear range of 1.0 × 10 −7 to 1.0 × 10 −1 mol L −1 with a low detection limit of 3.31 × 10 −8 mol L −1 . The working pH was 2.3−6.5 and the response time was 6 s. The fabricated sensor was highly selective for Al(III) ions. The response mechanism and surface reaction have been studied via scanning electron microscopy combined with energy-dispersive X-ray analysis and Fourier-transform infrared analysis.

“…They can, therefore, be used in biological applications such as cancer treatment ( Gao et al, 2018 ; GAO, 2019 ; Uthappa et al, 2019 ; Jiang et al, 2021 ). Several studies have shown that the metalorganic frameworks have beneficial aspects, including low cytotoxicity, host-guest interactions, hydrophobic/hydrophilic balance, biodegradability, body distribution, tissue accumulation, and excitability, allowing them to be used in biological applications for cancer treatment ( Tuncer et al, 2013 ; Ebrahimi et al, 2017 ). Therefore, we have chosen one type of Al-MOFs as a carrier for the anti-proliferative herbal extract.…”

In this study, novel nanostructures of aluminum base metal-organic framework (Al-MOF) samples were synthesized using a sustainable, non-toxic, and cost-effective green synthesis route. Satureja hortensis extract was used as an effective source of linker for the development of the Al-MOF structures. The Fourier-transformed infrared (FTIR) spectrum confirmed the presence of characterization bonds related to the Al-MOF nanostructures synthesized by the green synthesis route. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses revealed that the sample synthesized by Na2-CA was composed of multilayers, although it was agglomerated, but it had dispersed and occurred in spherical particles, indicating active organic matter. N2 adsorption/desorption isotherms demonstrated the significant porosity of the Al-MOF samples that facilitate the high potential of these nanostructures in medical applications. The anticancer treatment of Al-MOF samples was performed with different concentrations using the MTT standard method with untreated cancer cells for 24 and 48 h periods. The results exhibited the significant anticancer properties of Al-MOF samples developed in this study when compared with other MOF samples. Thus, the development of a novel Al-MOF and its application as a natural linker can influence the anticancer treatment of the samples. According to the results, the products developed in this study can be used in more applications such as biosensors, catalysts, and novel adsorbents.

A composite paper was designed in order to remove dyes and heavy metal ions in wastewater, which was prepared by assembling NH 2 -Cu-BDC layer by layer on the surface of the carboxymethyl-modified filter paper (CMFP). The prepared composite paper (Cu-MOFs/CMFP) shows the ability to capture dyes and metal ions, and the dye and metal solution can be separated by simple filtration on the MOF paper at the same time. The application of 30-layer Cu-MOFs/CMFP in the removal of pollutants in simulated wastewater was discussed, and it was found that Cu-MOFs/CMFP can simultaneously remove dyes and heavy metal ions with removal rates close to 90%. In addition, Cu-MOFs/CMFP can be reused after a simple washing process and maintains prosperous dye capture ability. The successful development of this technique provides a new strategy to design new materials for the removal of organic dyes and heavy metal ions in wastewater.
