“…Fluorescent materials, particularly blue fluorescent materials have gained strong interest because blue fluorescence is one of the key color components required for full-color EL displays and blue fluorescent materials are still rare up to now [1][2][3][4][5]. Recently, 4,4′-bipyridine (bipy) with delocalized -electrons of the pyridyl rings obtains increasing attention in preparing light emitting complexes in different technical applications, such as emitting materials for organic light emitting diodes, sensitizers in solar energy conversion, chemical sensors and so forth [6][7][8][9].…”

ABSTRACT.[Sm(H2O)4(NO3)3](4,4'-Hbipy)2(NO3)2 (1) (bipy = bipyridine) has been synthesized via hydrothermal reaction and characterized by X-ray diffraction. The title complex features an isolated structure, based on discrete 4,4'-Hbipy moieties, isolated nitrates and [Sm(H2O)4(NO3)3] species. The samarium ion is in a distorted bicapped square antiprism environment, coordinated by three bidentate nitrates and four coordination water molecules. The 4,4'-Hbipy moieties, isolated nitrates and [Sm(H2O)4(NO3)3] species are held together via hydrogen bonds and … interactions to form a 3-D supramolecular framework. Luminescent investigation reveals a strong emission in blue region. Optical absorption spectrum of 1 reveals the presence of an optical gap of 3.60 eV.

“…The order of interaction energy is Cu 2 + À S1 > Ni 2 + À S1 > Zn 2 + À S1. The above metal ions were selected based on their electronic configurations; Ni 2 + , Cu 2 + , and Zn 2 + with d 8 , d 9 , and d 10 configurations respectively. Irrespective of the similar size of the above metal ions, the Cu 2 + À S1 complex showed the highest interaction energy because of the existence of favourable NCI with the ligand S1.…”

Selective Detection of Copper Ions and Biological Activities of Isoniazid Schiff Bases

Following mechanical milling, the condensation reaction of the corresponding heterocyclic aldehydes with Isoniazid yields the Schiff base (E)‐N′‐((1H‐pyrrol‐2‐yl) methylene)isonicotinohydrazide (S1) and (E)‐N′‐(Thiophen‐2‐ylmethylene)isonicotinohydrazide (S2) supported heterocyclic derivatives. The structures of the Schiff bases, S1 and S2 were confirmed by 1H NMR, 13C NMR and IR spectroscopy. Copper ions (Cu2+) were trapped by S1 in DMSO to form the yellow‐coloured complex Cu‐(E)‐N′‐((1H‐pyrrol‐2‐yl)methylene) isonicotinohydrazide (Cu2++S1) with high sensitivity and selectivity. But the same ligand S1 could not be able to capture other metal ions tested for this work (namely, Co2+, Ni2+, Zn2+, Mn2+, Hg2+, Cd2+, Pb2+, Fe2+, and Fe3+) in DMSO. UV‐visible spectroscopic results confirmed the complex formation (Cu2++S1) with copper ions, but not with the other ions. Analysis of non‐covalent interactions (NCI) of ligand S1 with Ni2+, Cu2+ and Zn2+ in DMSO were investigated by density functional theory (DFT). NCI analysis of S1 by Cu2+ ions in DMSO was in good agreement with the experimental results. S2 did not react with any metal ions used in this study to form a complex in DMSO and the same was confirmed by UV‐Visible spectra. Reasonably good antibacterial activity was observed with S1, S2, Cu2++S1 compared to amoxicillin against Gram‐negative bacteria (K. pneumoniae, E. coli), Gram‐positive bacteria (S. aureus, S. pneumoniae), and fungal strain (C. albicans).

“…A trace amount of Cu 2+ is considered an essential nutrient for the human body [7]. Cu 2+ is the main component of a variety of enzymes such as superoxide dismutase (SOD1), cytochrome−c−oxidase (Cyt−O), tyrosinase, etc [8]. Its versatile role in chemistry, biochemistry, industry, and the medicinal field allows it to easily contaminate our environment [9].…”

A Quinoxaline−Naphthaldehyde Conjugate for Colorimetric Determination of Copper Ion

et al. 2022

View full text Add to dashboard Cite

This work facilitates detection of bivalent copper ion by a simple Schiff base probe QNH based on a quinoxaline−naphthaldehyde framework. The detailed study in absorption spectroscopy and theoretical aspects and crystal study of the probe and probe−copper complex has been discussed. The detection limit of the probe in the presence of Cu2+ is 0.45 µM in HEPES−buffer/acetonitrile (3/7, v/v) medium for absorption study. The reversibility of the probe−copper complex has been investigated by EDTA. The selective visual detection of copper has been established also in gel form.
