摘 要:目的与方法合成一个新的配体HPIA及其钌(Ⅱ)多吡啶配合物[Ru(bpy)2(HPIA)]ClO4(bpy=2,2′-联吡啶,HPIA=2-(2-羟基苯基)咪唑并[4,5-f]苊),用元素分析、电喷雾质谱、快原子轰击质谱、核磁共振谱表征配体及配合物;用电子吸收光谱和黏度测试研究配合物与DNA的作用方式。结果与结论配合物[Ru(bpy)2(HPIA)]ClO4与DNA之间通过插入作用结合。A new ligand HPIA ( 2-(2-hydroxyphenyl) -imidazo [ 4,5-f] acenaphylene, bpy = 2,2 ′-bipyridine ) and its ruthenium ( Ⅱ ) complex [ Ru (bpy) 2 (HPIA) ] C104 have been synthesized and characterized by elemental analysis, mass spectra and ^1 HNMR. The electrochemical behaviors of the complex were investigated by cyclic vohammetry. The DNA-binding properties of the complex were studied by spectroscopic methods and viscosity measurement. The experimental results indicate that the complex [ Ru( bpy)2 (HPIA)] ClO4 interacts with calf thymus DNA (CT-DNA) by intercalative mode into the base pairs of DNA.
