A copper(II) complex of the non-symmetric bidentate ligand 2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine (L1) is reported. The single-crystal X-ray structure of aqua-[aqua/chlorido-(0.49/0.51)](2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine)-copper(II) 0.49-chloride 1.51-hydrate, [CuCl1.51(C10H13N7S)(H2O)1.49]Cl0.49·1.51H2O or [(L1)Cl1.51(H2O...

A [Cu(II)16] wheel was isolated serendipitously from the reaction of acetylacetone dioxime with copper(ii) chloride and lanthanide ions in a reaction initially designed to produce heterometallic 3d-4f cages. The ligand has been transformed in situ to three different forms, all found within the [Cu16] wheel, with the original ligand completely absent.

A disposable sensor has been developed for the measurement of copper(II) concentration in aqueous solution based on a change in the fluorescence of porphyrazine 2,7,12,17-tetra-tert-butyl-5,10,15,20-tetraaza-21H,23H-porphine (TP). The sensor was constructed by spin-coating a polyester support with a PVC solution containing TP, a plasticizer, the chelating agent Zincon and the ion-pairing benzet...

Different weight amounts of graphene oxide (GO) were solution-dispersed with the precursor of polyimide (PI) and poly(amide-imide) (PAI) to synthesizen PI/GO or PAI/GO composite films after the imidization process. The addition of trimellitic anhydride chloride (TMAC) in PAI/GO matirx provides the interaction between amide group on PAI and carboxy/hydroxyl groups on GO.The effects of TMAC and G...

Copper(II) Chloride binuclear complexes with variously substituted 2,6-diphenly piperidin4-ones [Cu2LCl4(H2O)3] have been synthesized and characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, thermal and spectral studies. Molar conductance data show that these complexes are non-electrolytes. The presence of three coordinated water molecules is confirmed b...
