Synthesis, Spectroscopic, and Electrochemical Characterization of a Schiff Base: 4,4′-bis[(4- diethylaminosalicylaldehyde)diphenyl methane]diimine and Its Complexes With Copper(II), Cobalt(II), and Cadmium(II)
摘要:
The synthesis of a new ligand tetradentate Schiff base: 4,4'-bis[(4-diethyl aminosalicylaldehyde) diphenyl methane] diimine (H2L), obtained by condensation of 4,4'-diaminodiphenyl methane with 4-diethylaminosalicylaldehyde, and its complexes with copper(II), cobalt(II) and cadmium(II), is described. The metal complexes were characterized by elemental analysis, by UV-visible, infrared, and EPR spectroscopy, by cyclic voltammetry, and by thermal analysis (DTA-TG). The coordination of the metal ions to the ligand occurs through the N2O2 system. Thermal studies indicate that the ligand is more stable than the metal complexes (up to 310 degrees C).

Imine linked "on-off" multi-responsive and selective chemosensor has been synthesized and evaluated for cation recognition properties. The receptor shows high sensitivity and selectivity for Zn2+ through changes in fluorescence intensity based on ESIPT and charge transfer (CT) mechanism. The Zn2+ complex of the receptor can be used for phosphate quantification and for recognition of phosphorylated biomolecules through cation displacement approach. (C) 2013 Elsevier B.V.

A dipodal reversible colorimetric trivalent metal ion chemosensor (L) has been designed and synthesized. The chemosensor L successfully detects Al3+, Fe3+ and Cr3+ based on binding site-signaling approach and it has practical application.
