Luminescent Sensing of 1,3,5‐Trinitrotoluene Using a Schiff Base Ligand and Cd(II) Complex: Structural and Photophysical Investigations

Applied Organometallic Chemistry, Год журнала: 2025, Номер 39(6)

Опубликована: Май 2, 2025

ABSTRACT The Schiff base (H 2 L) was synthesized by condensing 2‐amino‐6‐methyl‐4,5,6,7‐tetrahydrothieno[2,3‐ c ]pyridine‐3‐carboxamide with 5‐bromo‐2‐hydroxybenzaldehyde in a 1:2 M ratio, yielding the product high efficiency. This then formed coordination complex Cd(II) 1:1 resulting [H LCd(H O) ]·1.5H O. synthesis and structural characterization of H L its were carried out using various techniques, including microanalysis (CHNS), FTIR, 1 13 C‐NMR, mass, UV–visible, magnetic susceptibility, thermogravimetric analysis (TGA), fluorescence spectroscopy. spectral data suggested that adopted an octahedral geometry. In addition to studies, properties investigated. Sensor for detecting nitroaromatic compounds assessed Both exhibited sensitivity detection 1,3,5‐trinitrotoluene (TNT). Specifically, demonstrated low limit (LOD) 0.094 μM linear range 1–10 μM. studies revealed displayed strong emissions. Furthermore, employed TNT through quenching, showing excellent selectivity sensitivity.

Supramolecular Self‐Assembly of Novel Double Chloride‐Bridging Trinuclear Ni(II) Mono‐Salamo‐Type Cluster: Experimental and Theoretical Analysis

Applied Organometallic Chemistry, Год журнала: 2024, Номер 39(1)

Опубликована: Сен. 27, 2024

ABSTRACT A mono‐salamo‐type ligand H 2 L was prepared to utilize 3‐methoxysalicylaldehyde and a semi‐salamo‐type compound, its novel trinuclear Ni(II) cluster with two significantly various configurations in the solid state obtained by reaction of ions. The structure validated x‐ray technique, ions exhibited hexa‐coordinated twisted octahedrons. Its structural formula is [Ni 3 (L) ( μ ‐Cl) (EtOH) ]. Chloride have also successfully double bridged participate coordination, play critical impact configuration's stability charge balance. Two solvent ethanol molecules are participated coordination. coordination ratio metal ion verified be 2:3 UV–Vis absorption titration spectroscopy. HOMO LUMO energies frontline molecular orbitals complex were analyzed DFT calculations, energy gap value 4.29 eV, that 0.72 eV. combined decreased produced more active complex. Furthermore, Hirshfeld surface analysis visualizes weak interactions crystalline molecules, these abundant an especially effect supramolecular self‐assembling. fluorescent researches proclaimed fluorescence intensity compared ligand, suggesting this greater promise for sensing.
