The interaction of Ru(phen) 2(dppz) 2+ (phen=1,10 phenanthroline,dppz=dipyrido[3,2 a:2′,3′ c]phenazine) and the calfthymus DNA were studied with fluorescence and ultraviolet visible absorption spectroscopy....The interaction of Ru(phen) 2(dppz) 2+ (phen=1,10 phenanthroline,dppz=dipyrido[3,2 a:2′,3′ c]phenazine) and the calfthymus DNA were studied with fluorescence and ultraviolet visible absorption spectroscopy. The ultraviolet visible absorption spectrum of Ru(phen) 2(dppz) 2+ , calfthymus DNA, and their interaction demonstrated that Ru(phen) 2(dppz) 2+ intercalated into the double helix of DNA via the ligand dppz. Fe(CN) 6 4- and NaCl can not quench the fluorescence of Ru(phen) 2(dppz) 2+ DNA, which was in agreement with the intercalation mode.展开更多
The fullerene complex, η 2 C 60 [Ru(NO)(PPh 3)] 2, has been prepared by the reaction of C 60 with Ru(NO) 2(PPh 3) 2 under a nitrogen atmosphere and refluxing.

The new complex was characterized by means of elemental analysis, IR, XPS, electronic spectra and 31 P NMR. The results show that the complex of η 2 form can be formed by C 60 bonding to Ru(NO) 2(PPh 3) 2 in the σ π way and there is hyperconjugation effect in the molecule. So electrons will flow easier and photoelectric effect for this new compound is expected. In addition, the structure of the complex has been supposed. The ruthenium is 4 coordinate in the complex, bonding to two carbon atoms, to one PPh 3 and to one NO.展开更多
The interaction of ruthenated porphyrin [Ru(bpy) 2(MPyTPP)Cl] + with CT-DNA was investigated with UV-Vis and fluorescent spectrum. It is found that [Ru(bpy) 2(MPyTPP)Cl] + binds to CT-DNA with a high affinity.
Tris(bipyridine)ruthenium(Ⅱ)(Ru(bpy) 2+ 3) was incorporated into mesoporous silicate MCM 48. X ray diffraction and emission spectroscopy were used to investigate the products, Ru(bpy) 2+ 3/MCM 48.

X ray diffraction and emission spectroscopy were used to investigate the products, Ru(bpy) 2+ 3/MCM 48. The emission spectra show that the wavelength of maximum intensity( λ max ) for Ru(bpy) 2+ 3 increases with the increase of Ru(bpy) 2+ 3 loading level in MCM 48. The photoluminescent property of Ru(bpy) 2+ 3/MCM 48 was investigated. It was observed that the wavelength maximum intensity( λ max ) for Ru(bpy) 2+ 3/MCM 48 was red shifted when acetone vapor was introduced. [WT5HZ]展开更多
