中文摘要: 由于杂金属簇合物的合成,结构和性质的重要性,本项目将研究以多核银簇为金属配体的杂金属簇合物的分步组装及其性质。设计合成同时含"软"和"硬"配位点的有机配体,然后通过"软"配位点与银离子组装形成多核银簇,进而利用所获得银簇上未配位的"硬"配位点来嫁接其它具有磁性或荧光性质的3d过渡金属或4f稀土金属离子,最终获得目标杂金属簇合物,并用光谱、质谱、核磁谱以及X 射线单晶衍射表征多核银簇金属配体及杂金属簇合物的分子结构以及测试它们的性质。

英文摘要: Due to the importance of the synthesis,structure and property of the heterometallic cluster, in this project, we will investigate the stepwise assembly of the heterometallic cluster based on polynuclear silver cluster as well as their properties. Firstly, we design and synthesize organic ligands incorporating both soft and hard coordination donors, which are used to construct the silver cluster with uncoordinated hard coordination sites. Secondly, the hard coordination sites are ligated to other 3d transtional metal or 4f lanthanide ions, forming the expected heterometallic cluster. The products including silver cluster metalloligand and heterometallic cluster will be fully characterized by spectroscopic analysis, mass spectrum, nuclear magnetic resonance and X-ray single crystal diffraction. The measurements of properties will be conducted as well.
