2,5-Dimercapto-1,3,4-Thiadiazole Tethered γ-Propylsilatrane: Syntheses, Characterization, UV-Vis and Electrochemical Studies

First Report on the Synthesis of Antipyrine Crowned Siloxy Framework: Optical Recognition of Fe2+and Hg2+Ions

“…Infrared and Multinuclear NMR ( 1 H, 13 C, and 29 Si) spectra of the synthesized silanes 2 and 3 and their respective silatranes 4 and 5 were obtained and verified in accordance with the structures of silane and their respective silatranes. In IR spectra of antipyrine schiff's base silanes (2 and 3), the appearance of the absorption band at around 3301 cm-1 due NH 2 group.…”

“…The signal appeared at 2.78 and 2.12 corresponds to the methyl group was associated with antipyrine. The respective 13 C NMR spectra for 4 and 5 exhibit carbon signals at 161 ppm around, assigned to the azomethine group (C=N), tie up of antipyrine, and silatranyl group, corroborate the synthesis. The silatrane 5 shows resonance at 57.17 and 59.18 ppm due to NCH 2 and OCH 2 in the atrane cage, respectively.…”

“…A unique feature of these silatrane molecules is the coordination bond between nitrogen and a silicon atom which reduces susceptibility to acid -base hydrolysis and hence imparts stability to the compounds. [13][14][15][16][17] In the present article, we have synthesized antipyrine blended azomethine based silatranes and considered the dynamic presentation of designed hybrid scrutinized as the receptor for various metal ion sensing. Now, with respect to the chemosensing potential of the receptor, the sensor exhibited selectivity, sensitivity, use of aqueous solution and low detection limit.…”
