Abstract

Abstract: 2,7-Bis(benzylamine carbonyl ethoxy) naphthaedi(L) and its rare earth picorate complexes [RE(pic)3]L2(RE=Y,La,Eu,Tb) were synthesized and characterized by 1H NMR, IR spectra, elemental analysis and molar conductivity. The complexation with ct-DNA was studied by spectrometry, cyclic voltammetry and, viscosity measurements in Tris-HCl buffer solution(pH=7.20), and the interaction strength was La(Ⅲ)＞Tb(Ⅲ)＞Y(Ⅲ)＞Eu(Ⅲ).

Key words: Amide-based open-chain crown ether, lanthanide complex, ct-DNA, intercalation
