Synthesis and charaterisation of phosphorescent copper (I) complexes for light emitting devices
… technology is focused on organo-transition metal complexes, which emit from the triplet excited state and exhibit bright phosphorescence. Efficient in devices have been reported using these luminescent materials, such as iridium and platinum complexes, however, rare metal abundance concerns, high …

Electron Transfer in a Series of Mixed-Valence Copper(ii)-Copper(i) Complexes (Epr, Electrochemistry, It Bands, Magnetism)
Three series of mixed-valence copper(II)-copper(I) complexes of macrocyclic ligands have been prepared to examine systematically the factors affecting intramolecular electron transfer. The mixed-valence complexes are similar to the one prepared by Gagne et. al. (J. Amer. Chem. Soc., 1979, 109, …

Syntheses and characterization of copper(I) complexes for study of dynamic supramolecular ring-chain equilibria and application as photoredox catalysts
… and π-acceptors. Thus, these ligands and their complexes, especially copper(I) complexes, have been the subject of a multitude of studies in organic, inorganic and supramolecular chemistry. By using the chelation of copper(I) ion species to phenanthroline ligands and its derivatives, a metalated …

Electrochemical and Spectroelectrochemical Studies of Complexes with Multiple Redox Centers
… spectroscopic properties of different types of complexes with multiple redox centers were investigated. Cyclic voltammetry was used as the main electrochemical technique along with thin-layer UV-visible and FTIR spectroelectrochemistry. The primary focus of this work was to elucidate the overall …

Diazine-bridged coordination polymers of copper and nickel : synthesis and thermal, spectral, structural, and magnetic properties
A large number of coordination compounds of copper(I), copper (II) and nickel (II) have been prepared and characterized by thermal, spectroscopic and X-ray diffraction methods as well as by elemental analysis and magnetic susceptibility measurements. The neutral ligands used in the study were …

Expanding the metallomics toolbox: Development of chemical and biological methods in understanding copper biochemistry
Copper is an essential trace element and required for various biological processes, but free copper is toxic. Therefore, copper is tightly regulated in living cells and disruptions in this homeostatic machinery are implicated in numerous diseases. The current understanding of copper homeostasis is …

An Investigation of the Structures, Properties and Possible Applications of Complexes of Metals with Organotellurium Compounds
… It is found that tellurides form quite stable complexes with metals of class (b) or softish character. Copper(I), rhodium(III) andrhodium (I) complexes with diaryltellurides were synthesised. Their structure, properties and uses were investigated with the help of various physical techniques. …
