Bis-triazole with indole pendant Organosilicon framework: Probe for recognition of Pb2+ ions

Abstract Trace lead (II) ions detection platform by adjoining an indole group, bis-triazole molecules and a silatranyl motif, has been proposed in this article. The receptor has been prepared by employing click chemistry methodology and the hybrid network was successfully identified by elemental analysis, IR and NMR (1H, 13C) spectroscopy. Absorption spectra analysis marked that the sensor exhibit an exclusively fastidious response to Pb2+ ions with a measured detection limit of 0.032µM at 1:1 stiochiometry. Further, computational studies have been carried out to get an insight into their structure and properties.
