Two new AIE-active dinuclear Schiff base Ir(III) complexes exhibit highly reversible piezochromic phosphorescence behaviour enabling the construction of a re-writable phosphorescence data recording device.

A number of new 1:1 complexes of SnMe(2)Cl(2) with unsymmetrical tetradentate Schiff base ligand with NNOS coordination sphere have been synthesized and fully characterized by a variety of physico-chemical techniques viz. elemental analysis, molar conductivity, (1)H and (119)Sn NMR, IR and mass spectroscopy. IR spectral data show that the fifth coordination position of tin atom is occupied by a...

The Cu(II), Co(II), Ni(II), Zn(II), Cd(II) and Hg(II) complexes of the Schiff base derived from reaction between benzofuran-2-carbohydrazide and acetophenone have been synthesized. The synthesized complexes have been characterized on the basis of elemental analysis, conductivity data, magnetic properties, IR and H NMR spectral studies. The spectral study shows that Schiff base act as bidentate ...

Three mononuclear Schiff-base–Ni( ii ) complexes act as electrocatalyst for hydrogen evolution reaction using acetic acid and trifluoroacetic the substrates. With increase in chain length of ligand, efficiency catalyst decreases.

Co(II) and Ni(II) complexes with a Schiff base, N-(2-furanylmethylene)-2-aminothiadiazole have been prepared and characterized by their physical, spectral and analytical data. The synthesized Schiff-bases act as tridentate ligands during the complexation reaction with Co(II) and Ni(II. metal ions. They possess the composition [M(L)(2)]X(n) (where M=Co(II) or Ni(II), L=, X=NO(3) (-), SO(4) (2-),...

Schiff bases of 3,4-dimethoxybenzenamine 1-25 were synthesized and evaluated for their antioxidant activity. All the synthesized compounds were characterized by various spectroscopic techniques. In addition, the characterizations of compounds 13, 15 and 16 were supported by crystal X-ray determinations and their geometrical parameters were compared with theoretical DFT calculations at the B3LYP...

In the title compound, [Zn(NCS)(C(16)H(18)N(4))]ClO(4), the Zn(II) atom is five-coordinated by four N atoms of the Schiff base ligand N,N'-bis-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine in the basal plane, and by the N atom of a thio-cyanate ligand at the apical position, forming a distorted square-pyramidal geometry. The r.m.s. deviation from a plane through the four N atoms of the Schiff b...

For the first time, functionalized mesoporous silica nanoparticles (MSNs) with dinuclear Schiff-base complexes were synthesized as attractive organic–inorganic hybrids and their capability investigated for loading antibiotic drugs immobilization of enzymes.

A media consisting of isatin-Schiff bases and its inclusion complexes with β-cyclodextrine was developed to maximize the production of antibiotics Hexaene H-85 and azalomycine B by Streptomyces hygroscopicus CH-7. The media with β-cyclodextrine inclusion complex of isatin-3-thiosemicarbazone resulted in the maximum antibiotics concentration of 493 μg/cm for Hexaene H-85 and 191 μg/cm for azalom...
