中文摘要：

使用P123（EO20PO70EO20）作为表面活性剂，并通过正硅酸乙酯与含可以水解烷氧基团的[Ru（Phen）2Phen—Si]^2＋功能化配合物的水解和共缩聚反应，成功地制备了共价嫁接[Ru（Phen）3]^2＋分子片断的复合SBA-15介孔杂化材料.用红外光谱和发光强度猝灭Stern-Volmer曲线对样品进行了表征，并分别用Demas双格位模型以及Lehrer模型对所获得的复合Ru-SBA-15样品的Stern-Volmer曲线进行了拟合.实验结果表明，所制备的传感样品对氧气具有较高的传感灵敏度.发光分子与分子筛之间产生强有力的CH2—Si化学键使得该杂化材料具有可逆的氧传感信号和较好的光化学稳定性.

英文摘要：

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）2Phen-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 Nz. The results show that the covalently-grafted sample shows reversible signals and higher photochemical stability since these Ru（ Ⅱ） molecules are strongly covalently-grafted to the Si-O network via the CH2-Si bonds.
