“…It is well known that the Zn II has d 10 configuration and cannot readily accept π‐electron density , . Hence, the red shifts of complexes 1 – 3 could be attributed to the intra‐ligand transition, which is in good agreement with other d 10 coordination compounds . Different from those of complexes 1 and 2 , strong luminescence emission is observed for 3 , the luminescent intensity of 3 is almost threefold larger than that of 2.…”

Their structures were determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses and IR spectroscopy. Notably, desamination reac-

“…The ligand 1,2-bis(4-pyridyl) ethane ( bpe ) has been extensively employed and investigated in the synthesis of novel compounds. , Due to its ditopic nature and the high flexibility conferred by its −CH 2 –CH 2 – backbone, it has been utilized as a building block in conjunction with various metal centers (Cu(II), Co(II), Ni(II), Fe(II), etc.) to achieve a wide range of coordination polymers (CPs) exhibiting distinct dimensionalities (1D, 2D, and 3D) , and properties. , Numerous investigations with these types of CPs have reported porosity (MOFs), magnetism, − and even luminescence depending on the chosen metal center. − The majority of CP syntheses have involved solvothermal methods conducted under elevated pressures and temperatures to facilitate crystallization processes, in situ redox reactions, and the formation of novel coordination environments. , While most research has focused on the structural attributes of these CPs, − a limited number of studies have explored their captivating properties, such as high quantum yield luminescence, exemplified by compound {[Cu 2 I 2 ( bpe ) 2 ]·Am} n , (Am = aniline, or p-toluidine). , Their remarkable optical properties suggest that CPs possessing similar characteristics could be of interest as downshifters, which are compounds capable of absorbing UV photons and converting them to visible light. Such downshifters could enhance the efficiency of commercial photovoltaic modules based on silicon solar cells .…”

Downshifters refer to compounds with the capacity to absorb UV photons and transform them into visible light. The integration of such downshifters has the potential to improve the efficiency of commercial photovoltaic modules. Initially, costly lanthanide derivatives and organic fluorescent dyes were introduced, resulting in a heightened module efficiency. In a novel research direction guided by the same physicochemical principles, the utilization of copper(I) coordination compounds is proposed. This choice is motivated by its simpler and more economical synthesis, primarily due to copper being a more abundant and less toxic element. Our proposal involves employing 1,2-bis(4-pyridyl) ethane (bpe), an economically viable commercial ligand, in conjunction with CuI to synthesize coordination polymers: [CuI(bpe)] n (1), [Cu 3 I 3 (bpe) 3 ] n (2), and [CuI(bpe) 0.5 ] n (3). These polymers exhibit the ability to absorb UV photons and emit light within the green and orange spectra. To conduct external quantum efficiency studies, the compounds are dispersed on glass and then encapsulated with ethylene vinyl acetate through heating to 150 °C. Interestingly, during these procedural steps, the solvents and temperatures employed induce a phase transformation, which has been thoroughly examined through both experimental analysis and theoretical calculations. The outcomes of these studies reveal an enhancement in external quantum efficiency with [Cu3I3(bpe)3] n (2), at a cost significantly lower (between 340 and 350 times) than that associated with lanthanide DS complexes.

A series of transition metal coordination complexes, {[Cu(3‐Sptta)2]·1/2H2O}n (1), {[Cd(3‐Sptta)2]·1/2H2O}n (2), [Zn(3‐Sptta)2(H2O)4] (3), and [Co(3‐Sptta)2(H2O)4] (4) were synthesized under solvothermal and solvent evaporation conditions using the newly designed heterocyclic N/NS carboxylate ligand [2‐(3‐pyridyl)‐1,3,4‐thiadiazole‐5‐]‐thio‐acetate (3‐Sptta) as a main building block. Their structures were determined by single‐crystal X‐ray diffraction analyses and further characterized by elemental analyses and IR spectroscopy. The four complexes exhibit structural diversity: complexes 1 and 2 exhibit similar 2D “wave‐like” double‐layer framework with two shares of mutually parallel left‐handed and right‐handed helical chains, whereas 3 and 4 present mononuclear structures. Moreover, the thermal stabilities of complexes 1–4 were investigated. The luminescent properties of complexes 2, 3 and the free ligand were also studied.
