【摘要】 合成和表征了1个新的钌(Ⅱ)配合物[R u(bpy)2(dpapz)](C lO4)2,其中bpy=2,2′-联吡啶,dpapz=联吡啶并[3,2-a:2,′3-′c]-6-氮杂-吩嗪.通过紫外可见光谱、荧光光谱、与溴化乙锭的竞争键合实验和粘度测量研究了该配合物与小牛胸腺DNA的键合性质,并研究了该配合物的紫外可见光谱和荧光光谱的溶剂变色性质.结果表明,该配合物是具有键合常数Kb=6.9×105L/m o l(50 mm o l/L N aC l)的DNA嵌入键合试剂和优良的荧光溶剂传感分子.更多还原

【Abstract】 A new ruthenium complex of -（ClO₄）₂, where bpy=2,2′-bipyridine, dpapz=dipyrido₆-aza-phenazine was synthesized, and characterized by microanalyses, IR and -{-}¹H NMR Spectra. The electronic absorption and emission spectral titration with DNA, DNA competitive binding with ethidium bromide, and viscosity measurements were carried out to study the calf thymus DNA binding properties of -（ClO₄）₂. The solvatochromism of the complex was also studied. The results indicate that the Ru（Ⅱ） complex acts as a DNA intercalator with a binding constant of 6.9×10⁵ L/mol at 50 mmol/L NaCl, and an emission sensor for solvent molecules.更多还原
