In this study, tris(2,2'-bipyridyl)ruthenium(II) (Ru(bpy)3(2+)), a strongly luminescent complex, has been physically adsorbed within the channels of mesoporous silica MCM-41 to obtain a photoactive hybrid material. In recent; years, the photochemistry and photophysics of Ru(bpy)(3)(2+) has attracted large attention; much of this interest stems from its electrochemiluminescent; properties and its redox behaviour. The physico-chemical properties of the hybrid H,U(bpy)(3)(2+) /MCM-41 material, characterised by X-Ray diffraction (XRD), volumetric analysis and FTIR, Diffuse Reflectance (DR.) UV-Vis and photoluminescence spectroscopies will be discussed. This new class of hybrid materials could be a photoluminescent and electrochemiluminescent probe for diagnostics.
