Functionalized organosilanes and their magnetic nanoparticles as receptor for Sn (II) ions detection and potent antioxidants

In this article, we proposed the synthesis of chalcone derived organosilanes based on polycyclic aromatic compounds. All the synthesized compounds were well categorized using numerous spectroscopic techniques such as IR, NMR (1H and 13C) and mass spectroscopy. Additionally, the compound is used for the recognition study towards the various metal ions which shows the great affinity towards Sn2+ ion. Organosilane was tie up to the nano surface of Fe-based magnetic silica, and various analytical and spectroscopic techniques were used to classify the obtained nanocomposites. Essentially, hybrid nanoparticles identification experiments illustrated the improved detection capabilities for Sn (II) ions with an even lower detection limit value. Furthermore, the synthesized orgaosilanes were investigated for their antioxidant activity by the decolouration of ABTS .+. In addition to the LanL2DZ base package, quantum mechanical calculations were carried out to explain the geometry and stability of the complex using DFT at B3LYP.
