摘要
The binding of coordination compound Ru(phen) to calf thymus DNA andherring Aparm DNA has been investigated by absorption,emission and of circulardichroism,spectroscopy. Measurement ot enantioselectivily combvined with photophysical experiment shows the bindins of Ru(phen),with calf thymus DNA is ofintercaiatively bound .mode but the binding of Ru(Phen),with herring spermDNA is of surface-bound mode.
