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
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.
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
