摘　　要：Ru(bpy)_(2)L_(2)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)(CH_(3)CN)_(2)](PF_(6)),的光物理及光化学反应进行了研究。The pholophysical and photochemical properties of the complex Ru(bpy)_(2)-(CH_(3)CN)_(2)(PF_(6))_(2) in 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 _(1)N H_(2)SO_(4) rnethanol.Emission lifetime is about 210 ns in methanol solution at 10℃. The complex to be irradiated at 254nm,283nm and 414nm in _(0.1)NH_(2)SO_(4) solution results in pseudo-first order photosubstitution reaction, producing cis-Ru(bpy)2-(CH2CN)(OH_(2))^(2+), the last photoprcduct is cis-Ru(bpy)_(2)(CH_(2))_(2)^(2+) . The quantum yields of disappearance for the complex are reported at irradiation wavelengths.
