NEW N^N LIGAND WITH HYDROPHYILIC SUBSTITUENTS FOR COORDINATION COMPLEXES BASED ON M(II) BIOMETAL IONS
Keywords:
3d transition metals, coordination complexes, photophysics, conductivity.Abstract
A new N^N chelating ligand based on 2,2’-bisquinoline functionalised with hydrophilic chains and its coordination complexes with Cu(II) and Zn(II) were synthesized and structurally characterized by IR and 1H NMR spectroscopies, atomic absorption spectroscopy and elemental analysis. An accurate photophysical characterisation and conductivity measurements showed the presence of different species in polar solvents solution and in mixtures of solvent/water. The ligand and its Cu(II) and Zn(II) complexes showed no antioxidant activity.
