The binding of coordination compound Ru(phen)₃²⁺ to calf thymus DMA and herring sperm DNA has been investigated by absorption,emission and circular dichroism spectroscopy. Measurement of enantioselectivily combined with photophysical experiment shows the binding of Ru(phen)₃²⁺ with calf thymus DNA is of intercalatively bound mode,but the binding of Ru(phen)₃²⁺ with herring sperm DNA is of surface-bound mode.
