Abstract

Schiff base alkyne 4 and it linked 1,2,3-triazole silane 5 has been synthesized, UV–visible sensing study of synthesized compound 4 and 5 have been performed, both are efficient to detect Zn(II) ion but the compound 5 has lower value of molar concentration to Zn(II) with limit of detection (LOD) value (1.4 x 10-6M), also the mode of binding interaction between compound 5 and Zn(II) was verified by computational Density functional theory (DFT) study was evaluated. Also the synthesized compound 5 has antioxidant properties by potential to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. UV–visible Sensing. [Display omitted] • Schiff base functionalized 1,2,3-triazole silane (5) has been synthesized. • Chemosensor 5 is essentially to detect Zn(II) ion analyte. • The proper binding site of Zn(II) to probe 5 is computationally evaluated through DFT study. • Antioxidant activity exhibited by the probe 5 is nearly as potential as Ascorbic acid. Schiff base linked1,2,3-triazole silane 5 has been synthesized through the Schiff base terminated alkyne with azido via click chemistry,the compound 4 structure elucidated through X-ray crystallography, and the compound 5 is well characterized through different techniques such asFT-IR, 1H and 13C NMR and Mass spectrometry. UV–visible sensing studies of synthesized compounds 4 and 5 have been performed, and both are efficient in detectingZn(II) ion, but compound 5 has imparted a higher mode of attraction to Zn(II) with limit of detection (LOD) value (1.4 x 10-6M) wherethe compound 4 is calculated to be (1.25 x 10-5M). By Job's method, the stoichiometric ratio of compound 5 and Zn(II) iscalculated to bea 1:1 ratio. The complex of compound 5 with Zn(II) was prepared. A radical and oxidative species are responsible for the deteriorating of stabilized molecules. The synthesized compound 5 hasantioxidant propertiesthat can potentially scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. Further to verify the mode of binding interaction between compound 5 andZn(II), computational Density functional theory (DFT) study was evaluated. [ABSTRACT FROM AUTHOR]
