A new ruthenium(Ⅱ) complex containing aliphatic polyamine [Ru(dipn)(tpy)](ClO4)2 (1), (tpy and dipn stand for 2,2′:6′2″-terpyridine and N-(3-aminopropyl)propane-l,3-diamine, respectively) was synthesized and characterized by EA, ESMS, UV-Vis and CV. The DNA-binding behaviors of this complex were studied by absorption titration, EB-competition fluorescence spectra and viscosity measurements, compared with those of it's series compounds [Ru(dipn)(dptp)](ClO4)2 (2) and [Ru(dipn)(pat)](ClO4)2 (3) (dptp=2-(5,6-diphenyl-1,2,4-triazin-3-yl)-1,10-phenanthroline; pat=9-(1, 10-Phenanthrolin-2-yl) acenaphtho[ 1,2-e][ 1,2,4]triazine). The results indicate that the three complexes interact with DNA in different mode: electrostatic attraction, partial intercalation and intercalation for 1, 2and 3, respectively. Their DNA affinities are in order: 1 ＜ 2 ＜ 3.
