Ferrocene Macrocyclic Schiff Base Complex: Synthesis, Structure and Recognition Properties for Dual Hg2+ and Cu2+
- 25 Downloads
A probe based on ferrocene structure has been designed, synthesized and elucidated from the single crystal X-ray method. It demonstrated fluorescence response to Hg2+ and Cu2+ in CH3OH. The results indicated that the title complex could be applied in the multianalyte detection. Binding ability of receptor 3 in CH3OH was tested for various cations (Fe3+, Co2+, Cu2+, Zn2+, Cd2+, Hg2+, Pb2+, and Ba2+ in water). The computed binding constants for Hg2+ and Cu2+ indicated a distinct absorbance shift. The receptor is an attractive array due to its distinct absorbance shift profile in a semi-aqueous phase, making it applicable in biology, environmental sciences and material chemistry.
