Description
Summary:Herein, a novel optical chemosensor, ( = 2, 6-di((E)-benzylidene)-4-methylcyclohexan-1-one), was designed/synthesized and characterized by H-NMR and FT-IR spectroscopy. The experimental observations indicated that is an efficient and selective chemosensor towards Cd , even in the presence of other metal ions, such as Mn , Cu , Co Ce , K , Hg , and Zn in the aqueous medium. The newly synthesized chemosensor, , showed a significant change in the fluorescence emission spectrum upon coordination with Cd . The formation of the Cd complex with was confirmed from the fluorometric response. The 1:2 combination of Cd with was found optimum for the desired optical properties, which was confirmed through fluorescent titration, Job's plot, and DFT calculation. Moreover, showed high sensitivity towards Cd with a very low detection limit (19.25 nM). Additionally, the was recovered and recycled by the addition of EDTA solution that combines with Cd ion and, hence, frees up the chemosensor.
