This study reports the first synthesis of aryl-alkyl ether functionalized silatrane for the selective recognition of Al3+ ions using cyclic voltammetry. The prepared compounds were well characterized and their potential as receptors for Al3+ ions was demonstrated. The real-time application of the synthesized sensors was confirmed through the detection of Al3+ ions in tea leaves.
The present work reports for the first time the preparation of aryl-alkyl ether functionalized silatrane for the selective recognition of Al3+ ions using the cyclic voltammetry technique. The synthesis was achieved through a condensation reaction followed by transesterification methodology to obtain organosilatranes in good yields. The prepared compounds were well characterized by IR, NMR (H-1 and C-13) and mass spectral analysis and the structure of one of the molecules was further confirmed by X-ray crystallography, which showed a triclinic crystal system with a P1 space group. The electrochemical behaviour was studied by employing square wave voltammetry (SWV) using a gold electrode to investigate the receptor action of the synthesized organosilatranes. A detection limit of 48.9 nM and competitive binding results suggest the significant receptor potential of organosilatranes for the detection of Al3+ ions. Moreover, the real time application of the prepared sensors was confirmed by the determination of Al3+ ions in tea leaves.
