A New Synthesis of Ferrocene Derived Schiff Base Sensor to determination of Zn2+/Cd2+ ions

The development of chemical sensors for the detection of heavy and transition metals is currently of great importance in supramolecular chemistry[1]. In this direction, ferrocene and derivatives for providing energy and electrons are used in fluorescence studies as chemosensors[2,3]. the design of single fluorescent probes that can report Zn2+ and Cd2+ with distinct fluorescence signals still attracts great attention because it is relatively challenging to discriminate between these two kinds of metal ions due to the fact that they lie in the same group in the periodic table. Fluorimetric studies has simple and high sensitivity to discrimination[4]. In this study, a novel ferrocene-based Schiff base (3) was synthesized. This compound was characterised by elemental analysis, FT-IR, 1H NMR and 13C NMR spectroscopy. Sensor 3 used as a sensor for the determination of heavy transition metal ions out of Zn2+ and Cd2+ ions using Fluorogenic method. The resulting data expressed the synthesized sensor was found to be good selective against Zn2+ and Cd2+ ions.
