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．
A trifunctional siloxane prepolymer containing luminescent ruthenium (Ru (bpy) 3 2+] molecules was prepared by sol-gel method and prepared by spin coating and gel treatment. Film, the microstructure of the carrier and the microenvironmental effect of the luminescent molecules were investigated. Compared with the traditional TEOS / Ru (bpy) _3_ (2+) membrane system, PMA-TMS with long chain unsaturated ester groups ) / Ru (bpy) _3_ (2+) system has the characteristics of good film-forming properties, high quenching gas response and short response time.
