In situ Synthesis, Crystal Structure, XPS and Fluorescent Property of a Novel Two-Dimensional Binuclear Copper(I) Tetrazole Complex

Valence-Oriented Electrosynthesis Strategies of Cu-Based 5-Nitrotetrazolate for Environmentally Acceptable Primary Explosives

“…The signal at a binding energy of 400.7 eV corresponds to the Cu–N bond. , In addition, the additional signal at a binding energy of 406.2 eV results from the O–NO bond of the -NO 2 group, further proving the existence of the nitrotetrazolate group structure. The high-resolution XPS spectrum of Cu 2p (Figure d) proves that the Cu exists only in the form of Cu + (932.0 eV) on the surface of CuNT. , On the basis of this result, the successful electrosynthesis of CuNT from the Cu precursor is strongly confirmed. The formation process of CuNT can be postulated as follows.…”

Influence of reaction temperature and stoichiometry on the coordination mode of a multidentate pyridylpyrazole ligand in Co(ii) complexes: from a 0D mononuclear structure to 3D frameworks

“…54 However, another strong peak at about 612 nm (shoulder) was observed in the spectra of 2 and 3 probably arising from metal-to-ligand charge transfer (MLCT). 55…”

“…54 However, another strong peak at about 612 nm (shoulder) was observed in the spectra of 2 and 3 probably arising from metal-to-ligand charge transfer (MLCT). 55 The UV-vis absorption spectra and luminescence spectra of H 2 ppza and 1-3 in 10 −5 M DMSO solutions were also assessed. As shown in Fig.…”

Two fluorescent copper phosphonate complexes for sensing antibiotics, ketones and Fe3+ in water

“…Figure 2c and d According to previous literature reports, when the central copper atom in the complex is monovalent, it usually displays 3 or 4 coordination mode, while divalent copper shows 5 or 6 coordination mode. [36][37][38] Although the original intention of our experiment was to prepare the Cu(I) phosphonate complex, the coppers in the target complex was testified to be divalent. It is speculated that the monovalent copper ion undergoes an oxidation reaction during the solvothermal process.…”
