This dissertation aims at finding anticancer and antibacterial polynuclear complexes targeting DNA with high activity and low toxicity. Sixteen compounds were synthesized, and characterized by means of X-ray single crystal diffraction, elemental analysis, molar conductivity and IR, and the influencing factors on structures of the compounds have been investigated. The actions of these compounds to DNA were also investigated by spectral, electrochemical and hydromechanical methods.

本论文以DNA为靶点，以寻找新结构类型的高效、低毒的抗癌、抗菌多核配合物为目标，从分子设计出发，共合成得到了16个化合物的单晶结构，对其进行了结构表征，探讨了结构影响因素，并研究了其超分子结构；采用紫外-可见吸收光谱法、荧光光谱法、电化学和粘度法，从分子水平上研究了所得配合物与DNA的相互作用；在细胞水平上，研究了草酰胺桥联双核配合物的抗菌和抗肿瘤活性。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。

The results indicated that the highest yield of BOC-indigo was 97% in CH2Cl2, and the lowest one was in PGMEA. It showed that the yield of BOC-indigo increased with high polarity and low molecular volume of solvent.

从实验结果得知，以极性较强且分子体积较小的二氯甲烷作为反应溶剂，其合成隐性颜料产率可达到97.2%，较四氢呋喃产率多4.4%，且较丙二醇甲醚乙酸酯产率多7.4%。

In addition,most of theprevious studies are focused on a very narrowly-separated doublets(e.g.,hyperfinestructure,Stark or Zeeman splittings)in a closed system.In fact,the atomic ormolecular system,especially the excited one,is an open system,but there are only afew studies for it.

另外，以往研究的多能级系统中相邻两能级的间距都很小(通常为原子的超精细结构、斯塔克分裂或塞曼分裂)，且大多数理论研究基本上都集中于封闭系统；然而，实际原子或分子特别是激发态的原子或分子体系通常为一开放系统，对于这方面的研究也很少。
