Binding constants( K n + ) and the reaction model were obtained from their electrochemical behavior and electrochemical data. The binding constants( K 2+ ) for Cu(phen) 2+ 2 DNA and Cu(bpy) 2+ 2 DNA were 8 51×10 3 L·mol -1 and 3 27×10 3 L·mol -1 , and K +s were 3 09×10 4 L·mol -1 and 5 66×10 3 L·mol -1 respectively. The spectroscopic characteristics of the complexes of Cu(phen) 2+ 2 DNA and Cu(bpy) 2+ 2 DNA were studied in detail. Some significant spectroelectrochemical data were obtained. The interaction of DNA with complexes was described.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
