Two copper(I)–NHC complexes bearing an azide group were reacted with alkyne-decorated magnetic Fe3O4 nanoparticles without the use of external copper source. In case least sterically congested complex, resulting displayed a catalytic activity in copper-catalyzed alkyne cycloaddition and some reusability highlighting covalent grafting molecular catalyst by this mild simple strategy.

The spontaneous emission of volatile organic compounds (VOCs) from common household items presents physiological hazards when inhaled over long periods of time. As a result, developing economical and reliable methods of detecting VOCs in hermetically-sealed enclosures, such as those employed in transportation, are important in ensuring the safety of passengers. In this study, copper(I) iodide (...

CuI nanoparticles efficiently catalyzed the C-S cross coupling of aryl and alkyl thiols with aryl halides in the absence of ligands on water under mild conditions. A wide range of diaryl sulfides and aryl alkyl sulfides are synthesized in good to excellent yields utilizing this protocol. This procedure is particularly noteworthy given its mild conditions, avoiding the undesired formation of dis...

In this work, copper (Cu) nanoparticles with observable surface plasmonic resonance (SPR) peaks were synthesized by an in-situ method. Chitosan host polymer was used as a reduction medium and a capping agent for the Cu nanoparticles. The surface morphology of the samples was investigated through the use of scanning electron micrograph (SEM) technique. Copper nanoparticles appeared as chains and...

The lowering of the CuII→CuI reduction temperature for subnano CuO particles (ca. 1 nm) was demonstrated, compared to nanoparticles, which monitored by in situ XAFS H2-TPR experiments. enhanced performance with a release atomic oxygen from copper oxide is attributed surface-strained structure and elongation Cu−O bonds.

This study reports the simple process to synthesis of CuO/CuI nanocomposite in a non-aqueous solution. In the conducted experiments CuI and Dimethyl Sulfoxide (DMSO) were used as the precursors. Moreover, DMSO had role of solvent and ligand simultaneously. In experiments the effects of oleic acid as the particles size modifier, temperature and concentration were investigated. Crystalline struct...

Pure yellow (CuI)P4Se4 was prepared by reaction of stoichiometric amounts of CuI, red P, and gray Se in evacuated silica ampoules. The crystal structure was determined from single crystals at room temperature. (CuI)P4Se4 crystallizes in the orthorhombic system, space group Cmca with a = 14.770 (1) AÊ , b = 12.029 (1) AÊ , c = 12.449 (1) AÊ , V = 2211.9(6) AÊ , and Z = 8. The structure refinemen...

Copper iodide (CuI) thin films were grown on Si(100) substrates using a copper film iodination reaction method. It was found that γ-CuI films have a uniform and dense microstructure with (111)-orientation. Transmission spectra indicated that CuI thin films have an average transmittance of about 60% in the visible range and the optical band gap is 3.01 eV. By checking the effect of the thickness...
