The DNA interaction mechanism with a Dy(Ⅲ)complex based on indolecarboxylic acid
A new Dy(Ⅲ)-based complex[Dy(7AI3CAH)2(NO3)(H2O)2]was constructed using 7-azindole-3-carboxylic acid(7AI3CAH2)as the ligand.Elemental analysis,infrared spectroscopy,thermogravimetric analysis were used to determine the structure of the com-plex.Fluorescence spectroscopy and viscometry showed that the binding mode between the complex and calf thymus DNA(CT-DNA)was intercalation binding,and the complex showed good binding to CT-DNA.
