摘要 | Novel oxygen sensing materials consisted of [ Ru ( Phen)(3)](2+) portion covalently grafted to the functionalized mesoporous SBA-15 backbones are prepared by co-condensation of tetraethoxysilane(TEOS) and the functionalized Ru ( II) complex [ Ru ( Phen) (2) Phen-Si](2+) in the presence of Pluronic P123 surfactant as a template. The obtained oxygen sensing materials are characterized by Fourier transform infrared( FTIR) and luminescence intensity quenching Stern-Volmer curves. The Demas and Lehrer models are used to fit the obtained nonlinear Stern-Volmer curves. The functionalized mesoporous sensing materials appear to be highly sensitive to the O2 concentration in N-2.The results show that the covalently -grafted sample shows reversible signals and higher photochemical stability since these Ru( 11) molecules are strongly covalently -grafted to the Si-O network via the CH2-Si bonds. |
