Polymer Electrolytes for LIBs based on Perfluorinated Sulfocationic Nepem-117 Membrane and Aprotic Solvents

Polymer electrolytes have been obtained by using Nepem-117 membranes in a Li+ form intercalated by polar aprotic solvents, such as dimethylformamide, dimethyl sulfoxide (DMSO), and dimethylacetamide (DMA), and solvent mixtures, such as ethylene carbonate-propylene carbonate (EC-PC), EC-DMA, EC-PC-DMA, and EC-PCDMA-tetrahydrofuran. The obtained electrolytes have been characterized by IR impedance and 7Li pulsed field gradient NMR spectroscopy. Ion mobility was observed to increase with higher degrees of solvation of the membranes. A method is demonstrated to determine the solvent uptake corresponding to the percolation threshold. With comparable solvent uptake, materials containing a solvent with a higher permittivity and a lower viscosity have higher values of ionic conductivity. The membranes containing the three-component mixture of EC-PC-DMA show the highest ionic conductivity values (8.1 and 2.1 mS/cm at 25 and −20 °C, respectively). Such values exceed the conductivity of electrolytes on the basis of the Nafion membranes solvated with aprotic solvents.

A Novel Tetrazole-Oxadiazole Hybrid: Synthesis, Computational Insights, and Biological Evaluation as a Potential Anticancer Agent

Antonenko D., Skryl’nikova M., Mikolaichuk O. и др., Journal of Molecular Structure 2027 Vol. 1382 No. 1 Article 147918

This study reports the design, synthesis, and comprehensive experimental and computational evaluation of a novel isopropyl 2-((5-((5-phenyl-2H-tetrazol-2-yl)methyl)-1,3,4-oxadiazol-2-yl)thio)acetate. As the first investigation in a planned series, this proof-of-concept study concentrates on a single model compound to validate the virtually unexplored tetrazole–oxadiazole hybrid class as a promising scaffold for anticancer agents. The target compound was synthesized via S-alkylation of ...

A 2D chlorobismuthate(III) framework built via Cl2-mediated halogen bonding

Новиков А. С., Polyhedron 2026 Vol. 301 Article 118454

New dichloro-chlorobismuthate supramolecular hybrid, (Me3NH)2{[BiCl5](Cl2)}, has been prepared and characterized by X-ray diffractometry as well as Raman spectroscopy. The self-assembly of 2D dihalogen-halometalate architecture succeeds via Cl⋯Cl halogen bonds (3.066 and 3.543 Å). These features were assessed with DFT calculations and Interaction region indicator analysis. ...

Synthesis and photophysical properties of 3-azinyl-7-aminocoumarins: tuning solvatochromism, HLCT excited state, and static fluorescence quenching by picric acid

Новиков А. С., Journal of Photochemistry and Photobiology A: Chemistry 2026 Vol. 485 No. 1 Article 117796

A series of new coumarin-azine fluorophores based on 1,2,4-triazinyl and pyridinyl substituted derivatives of 7-aminocoumarin was synthesized via a nucleophilic substitution of hydrogen (SNH) reaction followed by an inverse electron-demand Diels–Alder transformation. The primary photophysical properties of 3-triazinyl coumarins and their pyridine analogs was investigated in toluene and acetonitrile solutions. Thus, the emission of the fluorophores in ...
