The mechanism of thermally activated delayed fluorescence (TADF) in molecules in aggregated or condensed solid states has been rarely studied and is not well understood. Nevertheless, many applications of TADF emitters are strongly affected by their luminescence properties in the aggregated state. In this study, two new isomeric tetradentate CuI complexes which simultaneously show aggregation i...

The anionic diamido N-heterocyclic carbene 1 is used to prepare a series of linear as well trigonal, heteroleptic CuI complexes with small molecular ligands such pyridine derivatives or triphenylphosphine. A key role lies in the versatile precursor for these complexes, moisture- and air-stable 1D coordination polymer [1·Cu]n composed only NHC ligand CuI, that copper linearly coordinated by carb...

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...

the mononuclear complex [cu(l)(ch3cn)(pph3)]clo4, (1), (l= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, ir, 1h nmr, uv-vis spectroscopic methods and x-ray diffraction. the complex crystallizes in the non-centrosymmetric space group p212121 in accord with the asymmetric (atropisomer) cu centre. its coordination polyhedron...

Reactions between copper(I) iodide and triphenylphosphine have been explored in solution and in the solid state and six luminescent coordination complexes have been obtained and characterized by X-ray diffraction and UV-vis spectroscopy and photophysics. Solid-state reactions of CuI with PPh(3) in different conditions (kneading, vapour digestion) and stoichiometries resulted in the formation of...

The use of weak bases and mild conditions is currently the most sustainable attractive synthetic approach for preparation late-transition metal complexes, some which are widely used in catalysis, medicinal chemistry materials science. Herein, cuprate, aurate or palladate species a continuous flow CuI, AuI PdII-NHC complexes reported. All reactions examined proceed under extremely make technical...

The mononuclear complex [Cu(L)(CH3CN)(PPh3)]ClO4, (1), (L= 2,5-diphenyl-3,4-bis(2-pyridyl)cyclopenta-2,4-dien-1-one), has been synthesized and investigated by elemental analysis, IR, 1H NMR, UV-Vis spectroscopic methods and X-ray diffraction. The complex crystallizes in the non-centrosymmetric space group P212121 in accord with the asymmetric (atropisomer) Cu centre. Its coordination polyhedron...

The mechanistic details associated with the generation and reaction of [CuO]+ species from CuI-[alpha]-ketocarboxylate complexes, especially with respect to modifications of the ligand supporting the copper center, were investigated (see scheme). Theoretical models were used to characterize the electronic structures of different [CuO]+ species and their reactivity in C—H activation and O-atom t...
