Abstract: [Ru(bpy)3]2+/MCM-41 composite material obtained by loading tris(2, 2' - bipyridine)ruthenium(Ⅱ) ([Ru(bpy)3]2+) in siliceous mesoporous MCM-41 was characterized by X-ray powder diffraction, UV-Vis absorption and emission spectroscopies.The absorption spectrum of [Ru(bpy)3]2+ /MCM-41 is similar to that of [Ru (bpy)3]2+ aqueous solution, whereas its emission spectrum exhibits hypsochromic shift compared to the solution spectrum.On the other hand, the peak position of the emission spectrum of [Ru(bpy)3]2+/MCM-41 shifts towards longer wavelength when the loading amount increases.
