摘　　要：采用溶胶－凝胶法制备了含发光三吡啶钌[Ｒｕ(ｂｐｙ)３_^(２＋)]分子的三官能度硅氧烷预聚液,并通过旋转涂敷及凝胶处理制备了高性能的薄膜,探讨了载体的微结构和发光分子的微环境效应．与传统的四官能度正硅酸乙酯(ＴＥＯＳ)/Ｒｕ(ｂｐｙ)_３_(２＋)膜体系相比,含长链不饱和酯基的甲基丙烯酸丙酯基三甲氧基硅烷(ＰＭＡ－ＴＭＳ)/Ｒｕ(ｂｐｙ)_３_(２＋)体系具有成膜性能好,气体的猝灭响应值高,响应时间短等特点．The new sol-gel-derived silica films containing unsaturated long chain ester moieties were fabri-cated by spin-coating on to glass substrates. The films were pre-doped with the oxygen-sensitive lumines-cent Ru(bpy)_3^(2+), whose emission are quenched in the presence of oxygen. Compared with traditional te-traethyl orthosilicate (TEOS) /Ru (bpy)_3^(2+) films, 3-(trimethoxysilyl)-propyl methacrylate (PMA-TMS)/Ru(bpy)_3^(2+) films were found to be better in film-formation property, higher in quenching response for oxy-gen and shorter in response time. All improvements are due to the unsaturated 1ong chain ester moieties inresultant sol-gel films.
