Abstract:

A new complex [Cu(Phen)(Nap)2]2·(EtOH)2·(H2O)2(Phen=1,10-phenanthroline; Nap=1-naphthoic acid; EtOH=ethyl alcohol) was synthesized. The compound was characterized by elemental analysis, FTIR, TG-DTG, single crystal X-ray diffraction. The complex is dinuclear copper(Ⅱ) structure. The electrochemical and luminescent properties of the complex was studied by cyclic voltammetry and emission spectrum. The interactions of the complex with calf thymus DNA(ct-DNA) has been studied by UV and fluorescence spectroscopy. The results show that the copper(Ⅱ) complex shows irreversible redox process, and possesses a fluorescent emission band at 416 nm, and this copper(Ⅱ) complex binds to ct-DNA in groove binding and its intrinsic binding constant Kb is 4.68×103 L/mol.

Key words: dinuclear copper(Ⅱ) complex, synthesis, crystal structure, DNA, electrochemical performance
