The interaction of the complexes with calf thymus DNA was studied by means of electronic absorbance spectra, flurescence spectra, circula r dichroic spectra and viscosity experiments. All the results indicate that the complexes may interact mainly with calf thymus DNA by intercalation and coordina tion binding.展开更多
