Kinetic and Theoretical Studies of 3,5-Dicyanothiophene Reactivity with Cyclic Secondary Amines in Water and Acetonitrile: Quantification, Correlation, and Prediction.

The kinetics of the σ-complexation reactions of 3,5-dicyanothiophene with a series of cyclic secondary amines - has been studied in water and acetonitrile at 20 °C. Through the linear free energy relationship (LFER) log = s ( + ), the electrophilicity parameter of 3,5-dicyanothiophene has been determined and then integrated into the electrophilicity scale established by Mayr. Molecular dynamics (MD) simulations have been employed to elucidate the reversal in reactivity order between piperidine and pyrrolidine observed in water.

DFT-Computational Modeling and TiberCAD Frameworks for Photovoltaic Performance Investigation of Copper-Based 2D Hybrid Perovskite Solar Absorbers.

In this work, we use a combination of dispersion-corrected density functional theory (DFT-D3) and the TiberCAD framework for the first time to investigate a newly designed and synthesized class of (CHN)[CuCl] 2D-type perovskite. The inter- and intra-atomic reorganization in the crystal packing and the type of interaction forming in the active area have been discussed via Hirshfeld surface (HS) analyses. A distinct charge transfer from CuCl to [CHN] is identified by frontier molecular orbitals (FMOs) and density of states (DOS).

Synthesis, characterization, crystal structure, and fabrication of photosensitive Schottky device of a binuclear Cu(ii)-Salen complex: a DFT investigations.

This work explores one centrosymmetric binuclear Cu(ii)-Salen complex synthesis, characterization, photosensitive Schottky barrier diode (PSBD) function, and DFT spectrum. The crystal growth involves HL and Cu(NO)·3HO in CHOH + ACN (acetonitrile) solvent medium. Herein, structural characterization employs elemental, IR/Raman, NMR, UV-VIS, DRS, SEM-EDX, PXRD, SCXRD, and XPS analyses.

Supramolecular clumps of μ-1,3-acetate bridges of Cd(II)-Salen complex: Synthesis, spectroscopic characterization, crystal structure, DFT quantization's, and antifungal photodynamic therapy.

The article divulges the crystal growth, synthesis, and X-ray structure characterization of one centrosymmetric cadmium complex, [Cd{CdL(μ-1,3-acetate)}] using Salen ligand (SL). The complex is further characterized using spectroscopic and analytical techniques, including DRS, SEM-EDX, PXRD, and ICP-MS. The crystallographic study showed that the complex has a monoclinic space 2/.
