中文摘要：
合成了两种新型钌多吡啶配合物：[Ru（bpy）2（PyIP）]^2＋（1）和[Ru（dmb）2（PyIP）]^2＋（2），采用元素分析、电喷雾质谱和’HNMR对其进行了表征．用紫外滴定、荧光滴定以及粘度的方法研究了两配合物与DNA的相互作用．实验结果表明，两种配合物均以插入方式与DNA结合，然而配合物1与DNA的结合比配合物2的要大．这种现象是由于辅助配体的不同而引起的．
英文摘要：
Two novel polypyridyl {PylP = 2-（pyren-1-yl）-lH-imidazo[4,5-f][1,10] phenanthroline, bpy = 2,2′-bipyridine, dmb = 4,4′-dimethyl-2,2′-bipyridine} ruthenium （ Ⅱ ） complexes [Ru（bpy）2（PyIP）]^2＋（1）and[Ru（dmb）2（PyIP）]^2＋（2） have been synthesized and characterized by elemental analysis, ES-MS and a H NMR spectroscopy. The DNA-binding of these complexes were investigated by spectroscopic methods and viscosity measurements. The experimental results indicate that both complexes 1 and 2 bind to calf thymus DNA in classical intercalation mode, and however, complex 1 intercalated more strongly than complex 2, due to the different ancillary ligands.
