5-[{(2-Hydroxynaphthalen-1-yl)methylene}amino]pyrmidine-2,4(1H,3H)-dione as Al3+ selective colorimetric and fluorescent chemosensor

Versatile coordination behaviour of a multi-dentate Schiff base with manganese(II), copper(II) and zinc(II) ions and their corrosion inhibition study

“…A number of transition metal complexes of aroylhydrazones have been reported to exhibit catalytic [10], sensing [11,12], corrosion inhibition [13] and biological activities [14][15][16][17]. High-spin Mn(II) materials can efficiently enhance the relaxation rates of water protons and thus act as contrast agents for magnetic resonance imaging (MRI) [18].…”

Recognition of Mg2+ and Zn2+ based on a naphthalene-based fluorescent probe by regulating solvents

“…As shown in Fig. 1, the spectrum of the free HL showed a maximum absorption band at 375 nm, which can be assigned to p?p ⁄ transition of naphthalene group [29][30][31][32]. With the increasing concentration of Mg 2+ , the absorption band at 375 nm gradually decreased and a new absorption band appeared at 439 nm with increasing intensity.…”

Synthesis, structure and characterization of a new noncentrosymmetric Zn(II) complex with the 2-amino-5-chloropyridine ligand (AClPy)

“…Hydrogens were included on calculated positions, riding on their carrier atoms, apart from those belonging to the amino groups, that were localized in the difference Fourier map and optimized to restrained positions. The Flack parameter [21] is -0.020 (10), indicating that the atomic arrangement corresponds to the absolute structure.…”

“…They are known to be a class of versatile ligands, allowing to generate a variety of molecular architectures and coordination polyhedra [3][4][5]. The metal complexes of such Schiff bases have been extensively used as biological probes [6], DNA cleaving agents [7], catalysts [8,9], sensing materials [10,11] and corrosion inhibitors [12]. In recent years, the coordination chemistry of N coordinated ligands has also received a lot of attention because of their relevance to biological systems [13].…”
