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).
- amide type open-chain crown ether,
- rare earth complexes,
- ct-DNA,
- intercalative binding mode
