中文摘要: 配合物结构与磁性的研究是配位化学研究的热点之一,在本项目的研究中,我们在以往工作的基础上,对以负电荷为辅助配体的金属-叠氮配合物进行深入研究,通过选择不同的负电荷配体和其它辅助配体来共同调控金属-叠氮配位聚合物的结构与磁性,探索结构与磁性之间的关系、总结其中的规律性,探索它们的材料性能与应用前景。在本项基金的资助下,我们根据已有的经验,把水热合成方法安全地应用到金属-叠氮配合物的合成中,催生了一些新型金属-叠氮配合物。通过合理的设计方案,成功地实现了对配合物配合维度的调控,随之优化了配合物的性质。在不断深入研究的过程中,把稀土离子成功地引到了金属-叠氮领域当中。对实验产物选择性地研究了它们的有关性能,探索了结构与性能的内在关系,发现了一些有趣的现象及规律,有关研究成果已在Dalton Trans., Eur. J. Inorg. Chem., J. solid. State. Chem.等国内外重要刊物发表SCI收录论文5篇,取得了一定的学术成绩,完成了本项目的既定目标。

英文摘要: The structure and magnetic properties of coordination polymers have attracted great attention in the field of chemistry and materials science. In this project, based on our past works,we studied on the fileld of metal-azide complexes with negetive charge ligand as co-ligand by selecting diffrent kinds of negetive charge ligand to adjast the structures and properties. Their structural chemistry, coordination chemistry, magnetic properties and emission properties, and the relationship between structure and properties have been well studied. In this project, we got satisfied result by hydrothermal method, which mean that the synthetic strategy and synthetic method are steady and believable. We have, thus, opened a new perspective to generate lanthanide-azido complexes for researchers. 5 papers have been published basing on these results in world leading journals including Dalton Trans., Eur. J. Inorg. Chem., J. solid. State. Chem. The main aims of this project have been well achived.
