摘要/Abstract

摘要： Ru(bpy)₂L₂类型配合物(bpy=2,2'-联吡啶,L为单齿配体)已有报道,本文对[Ru(bpy)₂(CH₃CN)₂](PF₆),的光物理及光化学反应进行了研究。

Abstract: The pholophysical and photochemical properties of the complex Ru(bpy)₂-(CH₃CN)₂(PF₆)₂in solvents and acidic solution were investigated. The complex exhibits stronger luminescence at 77K in solvents, The emission maximum is at 54Cnm and a second weaker band is at 580nm in methanol-ethanol. They are characterized by a band near G50nm and a second weaker band at 590nm in 1N H₂SO₄rnethanol.Emission lifetime is about 210 ns in methanol solution at 10℃. The complex to be irradiated at 254nm,283nm and 414nm in 0.lNH₂SO₄solution results in pseudo-first order photosubstitution reaction, producing cis-Ru(bpy)₂-(CH₂CN)(OH₂)²⁺, the last photoprcduct is cis-Ru(bpy)₂(CH₂)₂²⁺. The quantum yields of disappearance for the complex are reported at irradiation wavelengths.
