Dual detection highly selective colorimetric chemosensors for fluoride and copper(II) ions based on imine-phenol derivative

A simple dual detection using colorimetric chemosensor, imine-phenol derivative L (bearing a 2-iminephenol group as a binding unit and a-nitrophenylazo group as a signaling unit), were synthesized for a high yield in two simple steps. Complexations of chemosensor L with various anions in acetonitrile solvent and other metal ions in DMSO/H2O solvent were monitored by UV-visible spectroscopy. The results indicated that the chemosensor L showed high selectivity for F? and Cu2+ ions. Furthermore, the complexes for L-F? and L-Cu2+ were evaluated by computational chemistry using a B3LYP/6-31G (d,p) and a B3LYP/6-311G (d,p) level of calculation. The complexes between L with F? and Cu2+ were magenta and yellow colored, respectively. Chemosensor L can be applied for the analysis of F? and Cu2+ ions with naked-eye detection making colour comparisons between the standard and the real sample. Most importantly, semi-qualitative detection of Cu2+ in water solution were successfully carried out with the developed test kit using chemosensor L.

Synthesis and antibacterial activities of mixed ligands complexes of Cu(II) and Zn(II) containing tridentate azo anils ligands and bidentate oxalate ion

Mixed ligands complexes of copper(II) and zinc(II) were synthesized using azo anils ((HNPDBAB = 2-({2-hydroxy-5-[(4- nitrophenyl)diazenyl]benzylidene}amino)benzoic acid, HPIMNDP = 2-{[(2-hydroxyphen yl)imino]methyl}-4-[(4-nitrophenyl)diazenyl] phenol) and oxalate ion as a coordinating ligands. Elemental analysis, atomic absorption spectroscopy, FTIR, NMR, UV-visible. were used for the characterizations of synthesized azo anils ligands and their mixed ligands complexes. Distorted octahedral geometry was tentatively proposed for these new mixed ligands M(II) {Cu(II) and Zn(II)} complexes. Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Enterobacter aerogenes and Escherichia coli) were screen out for antibacterial activities of azo anils ligands, oxalic acid, metal salts and their mixed ligands M(II) complexes. The antibacterial activities were performed to assess the extent of inhibition potential of free ligand and their mixed ligands M(II) complexes. The results revealed that antibacterial activities of azo anils became more pronounced when these were coordinated to central metal atom.

Synthesis and biological activity evaluation of some binuclear metal complexes of Cu(II) and Zn(II) with tridentate schiff base ligands

A few kinds of new Schiff bases were synthesized by reaction of 2-aminophenol and corresponding synthesized azo compounds 3a-e. Further reaction of these Schiff bases 4a-e with transition metal salts as Cu(II) and Zn(II) gave corresponding binuclear complexes 5a-e and 6a-e. The antibacterial activity of prepared complexes was investigated against Staphylococcus aureus and Escherichia coli bacteria. The results for some compounds revealed a moderate to good inhibition against Staphylococcus aureus compared with penicillin zone of inhibition.

Simple and efficient colourimetric F-sensors and a test paper for fluorine

A series of colourimetric fluoride ion sensors bearing azo-phenolic hydroxyl and Schiff base groups were synthesised. In CH3CN solutions, these sensors showed colourimetric single selectivity for F-. An easy-to-prepare test paper based on the s
