Schiff base-functionalized silatrane-based receptor as a potential chemo-sensor for the detection of Al³⁺ ions

Abstract

Excess of Al(III) is considered as toxic for living organisms. By keeping harmful effects of Al(III) in mind, a new Schiff base functionalized silatrane as a potential Chemo-sensor for the...

Tetrazole conjoined organosilane and organosilatrane via the ‘click approach’: a potent Mycobacterium tuberculosis enoyl ACP reductase inhibitor and a dual sensor for Fe(iii) and Cu(ii) ions

“…The tetrazole appended silatrane (3) was investigated for optical recognition potential via absorption spectroscopy due to low cost and easy handling in comparison to other investigating techniques such as atomic absorption spectroscopy, chromatography, voltammetry, polarography and X-ray photoelectron analysis. 16 The designed ligand was found selective and specific only for Fe(III) and Cu(II) metal ions among different tested metals. Among all competitive metals, only the introduction of Fe(III) and Cu(II) caused a change in the absorptive response of constructed tetrazole.…”

“…The reaction mixture was stirred for 17 hours at room temperature. 16 After stirring, the reaction mixture was added to ice-cold water. The solid product was obtained after filtration and labelled as compound (1).…”

“…[13][14][15] The presence of transannular silicon and the nitrogen dative bond is responsible for the architectural beauty, structural stability and uniqueness of organosilatranes. 16 Organosilicon compounds have been successfully used in organic synthesis, sensing, catalysis, agriculture and medicine. [14][15][16][17] 'Click Chemistry', first introduced by Sharpless and coworkers, 18 has emerged as a powerful strategy for the molecular stitching of smaller fragments into complex molecules.…”

“…16 Organosilicon compounds have been successfully used in organic synthesis, sensing, catalysis, agriculture and medicine. [14][15][16][17] 'Click Chemistry', first introduced by Sharpless and coworkers, 18 has emerged as a powerful strategy for the molecular stitching of smaller fragments into complex molecules. The click route has now established a foothold owing to its remarkable efficiency, specificity, bioorthogonality and high yields, thus meeting the demands of modern-day chemistry.…”

Synthesis and Characterization of Antioxidant Biphenyl Appended 1,2,3‐Triazoles as Potential Chemo‐Sensor for Sn2+ Ions: Excellent Selectivity and Low Detection Limit

“…The invention and implication of sensors to monitor various analytes in the environment and biological systems is the new area of intrigue among researchers over other analytical methods due to operational simplicity, precise selectivity, rapid response, relatively low expense and easy operation. [23][24][25][26][27][28][29][30] Here, in the present work, we have synthesized and characterized biphenyl appended 1,2,3-Triazoles using click route. One derivative 4 a among triazoles has been explored for chemosensing properties by Ultraviolet and fluorescence spectroscopy.…”
