Therefore heteronuclear Cu-Ln compounds have commonly been synthesized with hetero-donor ligands comprising two types of ligating atoms coordinated each to Cu and Ln atoms, respectively.

因此通常用含有能分别和铜，稀土配位的两种配位原子的配体来合成异核Cu-Ln配合物。

Different from the conventional catalyst immobilization methods, the self-supporting strategy utilizes homochiral metal-organic coordination polymers generated by self-assembly of chiral multitopic ligands with metal ions without using any support.

与传统的负载模式不同，手性自负载催化剂通过含双或多官能团的手性配体与金属通过自组装形成一类有机-无机聚合物，因此无需使用任何载体，即能够有效地实现手性催化剂的回收和再利用。

Using Gassian98 with LANL2DZ basis sets, the quantum chemistry calculation of the model was performed.4. A series of ligands which all include imidazolyl group were designed and synthesized. The crystal structure of one of them was determined by X-ray diffraction.

PBIOM or benzylimidazoleand CoP in chloroform solution were mixed to complex the imidazolyl residue of the ligands with the fifth coordination site of CoP under nitrogen atmosphere to get CoP complexes.

PBIOM或苄基咪唑中的咪唑基与CoP在溶液中配位，得到的CoP-PBIOM或CoP-BIm络合物具有快速、可逆的氧结合特性。

There were five kinds of NpCpTiCl〓, in which Np was pyrolyl , indolyl ; 7-azoindolyl , indazolyl , and benzimidazolyl respectively. All of them were prepared by the reactions of CpTiCl〓 with the anions of the relevant ligands, and characterized by elemental analysis, IR, or NMR.

此外，半茂体系的催化活性都随铝／钛比的增加呈上升而后衰减型，当Al／Ti比为500左右时活性达到最高，这个值远低于茂金属催化剂活性达最高时的Al／Ti比，即茂金属配合物比半茂配合物需要更多的MAO来活化，并稳定形成的活性中心。

The intramolecular hydrogen bonding can extend the ligand planarity and increase the intercalative ability of the complex to DNA. It is concluded that the torsion between the aromatic rings of ligands, due to introduction of the bulky substituent, results in the complexes only to partially or non-classically intercalate into DNA.

能够使配体平面性增大的分子内氢键的形成，有利于配体对DNA的插入作用；但是，由大体积的取代基所引起的配体芳环间的扭转，致使配体只能&部分地&或&非经典地&插入DNA碱基对。

In this thesis, five polydentate ligands including azido, oxalate, terephthalic acid, isophthalic acid and Pyridine-2,6-dicarboxylic acid were used to construct new transition metal complexes (M = Ru, Fe and Zn). Eight new complexes as listed below were synthesized and fully characterized.

本论文以草酸根、叠氮根、对苯二甲酸、间苯二甲酸和吡啶-2，6-二羧酸等含O、N的多齿共轭配体为研究对象，合成了以下八个结构新颖的化合物，并对它们的结构和谱学性质进行了详细的表征。

In complexes 8～16 synthesized by hydrothermal method, most of the ligands adopt multidentate coordination modes joining several lanthanide ions into high-dimensional coordination polymers. And changing of 5-substituting group on isophthalic acid has a little effect on the coordinated abilities of the meta-carboxyl groups.

水热法制备的配合物8～16中，配体多采取多齿配位模式桥连多个稀土离子，形成高维配位聚合物，同时由于羧基氧原子和稀土离子的强的键合力，间苯二甲酸的5位取代基的变化对间位羧基的配位能力的影响不大。

Furthermore, the one-dimensional complexes 26 and 28 with strongπ-πpacking interactions are prepared from DMF solvent, which indicates that the traditional solvent volatilizing method could bring low-dimensional complex.4. By measuring the enthalpy changes of the liquid phase formation reaction for complexes a~e, and calculating the electronic densities of five 5-substituted derivation of isophthalic acid, we can make a conclusion that 5-substituted group changing of the ligand has a little influence on oxygen atoms of carboxyl groups.5. Fluorescence experiments of these complexes indicated that they could be used for luminescence materials in future.6. Using packing saturation rule we calculated and analyzed these series of complexes, and the results showed that the changes of complexes with changes of ligands could be explained from the rule.

在DMF溶剂中得到了具有强π-π堆积作用力的一维配位聚合物[Ln(5-NO_2-bdc)(NO_3)]Ln=Pr(26和Ho(28)，表明传统的溶剂挥发合成条件可以得到低维的配合物。4、通过配合物a～e的液相生成反应焓的测定，以及配体阳离子的电子密度计算，进一步佐证了间苯二甲酸的5位取代基变化对配体的羧基氧原子配位能力影响不大的结论。5、荧光特性表明此类配合物可以用于发光材料。6、利用堆积饱和规律对所得系列的配合物的进行计算和分析，发现随着配体的变化，配合物的变化可以从堆积饱和规律出发进行解释。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
