“…in DMF (3 mL) and sonicated for 5 min. The vial was then sealed and heated overnight at 100 • C. The resulting mixture was allowed to cool, and the resulting precipitate was collected by filtration and washed with DMF (3 × 1 mL) and then MeOH (1 mL) to yield a fine, pale-yellow solid (1)/a fine yellow solid (2). For FT-IR and NMR measurements, to eliminate the influence of DMF, the material was immersed in MeOH for 15 min with the solvent being exchanged with fresh MeOH (3 mL) every 2 min.…”

In this study, the synthesis of a Schiff base containing metal–organic frameworks (MOFs) of the UiO-67 family has been investigated. MOFs featuring free amine groups were successfully synthesized under mild solvothermal conditions using 2-amino-[1,1′-biphenyl]-4,4′-dicarboxylic acid and 2,2′-diamino-[1,1′-biphenyl]-4,4′-dicarboxylic acid as bridging ligands, resulting in MOFs with amine groups covalently linked to the bridging ligands. Both types of functionalized MOFs were post-synthetically modified with 4-formylbenzonitrile that resulted in imine formation. All the obtained compounds were characterized by PXRD, TGA, DTA, BET, NMR, and FTIR spectroscopy, while stability in water was monitored with SEM, EDS, and UV–VIS spectroscopy.

“…Luminescent metal-organic coordination polymer is an effective and convenient class of fluorescent sensing materials [ 8 ]. More and more of such materials are found to be capable of effective fluorescence sensing of heavy metals, industrial pollutants, pesticides, etc., with excellent sensing selectivity, sensitivity, and stability [ 9 , 10 , 11 , 12 ]. Among them, Cd-based coordination polymers showed good fluorescence sensing properties for different analysts, such as metal ions, anions, nitro-compounds, and so on [ 13 ].…”

Detection of nitro pollutants is an important topic in environmental protection. A total of 3 Cd (II) complexes (1–3) based on 3 soft organic isomers, n-(3,5-dicarboxylato benzyloxy) benzoic acid (n = 2, 3 or 4-H3DBB), and a linear N-donor ligand, 3-bis(imidazole-l-ylmethyl) benzene (3-bibz), have been synthesized hydrothermally. Structural diversity of Complexes 1–3 displays the architectural 2D or 3D change: Complex 1 exhibits a 2D network featuring tri-nuclear metal units, Complex 2 is a 3D framework based on similar tri-nuclear metal units, and Complex 3 shows a 3D network with binuclear units. Fluorescent sensing properties exhibited in all these complexes have been discovered to detect nitrobenzene (NB) selectively and sensitively. In particular, Complex 3 possesses high sensitivity for NB with the lowest detection limit of 1.15 × 10−10 M. The results of the theoretical calculation verified the fluorescence detection mechanism of NB by these Cd-based complexes. Therefore, these Cd-based complexes might be used as excellent luminescent sensors for NB.

“…XAS is a local and site-sensitive technique providing information about both the electronic and atomic structures around the absorbing center. Together, XANES/NEXAFS and XPS can provide information about the geometry of the absorbing atom [ 25 ] and structural defects [ 26 ], and, being elementally selective, they provide information about the chemical composition, presence of elements and functional groups on the surface [ 27 , 28 , 29 , 30 ], the oxidation state of elements [ 29 , 31 , 32 ], and the nature of chemical bonding between the CNT and MeO x causing the formation of the composite [ 33 ]. Analysis of up-to-date publications shows that the theoretical interpretation of XANES spectra of nanocomposites based on transition metal oxides and carbon nanotubes is rarely used due to the complexity of applying this technique to the study of nanocomposites.…”

Due to their unique physical and chemical properties, complex nanostructures based on carbon nanotubes and transition metal oxides are considered promising electrode materials for the fabrication of high-performance supercapacitors with a fast charge rate, high power density, and long cycle life. The crucial role in determining their efficiency is played by the properties of the interface in such nanostructures, among them, the type of chemical bonds between their components. The complementary theoretical and experimental methods, including dispersion-corrected density functional theory (DFT-D3) within GGA-PBE approximation, scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman, X-ray photoelectron, and X-ray absorption spectroscopies, were applied in the present work for the comprehensive investigation of surface morphology, structure, and electronic properties in CuOx/MWCNTs and NiOx/MWCNTs. As a result, the type of interfacial interaction and its correlation with electrochemical characteristics were determined. It was found that the presence of both Ni–O–C and Ni–C bonds can increase the contact between NiO and MWCNTs, and, through this, promote electron transfer between NiO and MWCNTs. For NiOx/MWCNTs, better electrochemical characteristics were observed than for CuOx/MWCNTs, in which the interfacial interaction is determined only by bonding through Cu–O–C bonds. The electrochemical properties of CuOx/MWCNTs and NiOx/MWCNTs were studied to demonstrate the effect of interfacial interaction on their efficiency as electrode materials for supercapacitor applications.
