用密度泛函理论,在B3LYP/LanL2DZ水平上,对系列钌多吡啶配合物的电子结构和DNA键合倾向进行研究,分析这些配合物的电子结构性质,合理地解释这三个配合物与DNA键合倾向性质。另外,用TDDFT方法,对三个配合物的电子吸收光谱进行计算和模拟,计算得到的电子吸收光谱和实验结果吻合较好,并研究配合物的主配体对电子吸收光谱的影响。
用密度汎函理論,在B3LYP/LanL2DZ水平上,對繫列釕多吡啶配閤物的電子結構和DNA鍵閤傾嚮進行研究,分析這些配閤物的電子結構性質,閤理地解釋這三箇配閤物與DNA鍵閤傾嚮性質。另外,用TDDFT方法,對三箇配閤物的電子吸收光譜進行計算和模擬,計算得到的電子吸收光譜和實驗結果吻閤較好,併研究配閤物的主配體對電子吸收光譜的影響。

Studies on the electronic structures and trend in DNA-binding affinities of a series of Ru(II)com-plexes have been carried out,using the density functional theory (DFT) at the B3LYP/LanL2DZ level. The electronic structures of these Ru(II)complexes were analyzed,and the trend in the DNA-binding constants (Kb)was reasonably explained. In addition,the electronic absorption spectra of these complexes were calcu-lated and simulated using the time dependent DFT (TDDFT). The calculated absorption spectra of these Ru(II)complexes are in good agreement with experimental results,and the effect of main ligands of complex-es on the absorption spectra was also investigated.
