中文摘要： 高核币金属簇合物由于其独特的组成与电子结构，在催化、传感、药物化学等方面具有广泛的应用前景。本项目选用巯基配体、炔基配体、膦配体等与币金属金、银、铜等组装，通过溶剂挥发、水热/溶剂热、离子热、微波加热等方法，在模板剂的诱导下合成系列高核币金属及异金属簇合物。研究这些高核币金属及异金属簇合物的结构和光学性能；将其中部分制成币金属团簇后研究团簇对重金属离子（汞（II）、铬（III）、镉（II）、铅（II）等）的光化学传感作用与传感机理。研究高核币金属及异金属簇合物的合成与自组装规律、结构特点以及结构-性能关系，为进一步设计合成具有光化学传感性能的“币金属团簇分子器件”提供理论基础和实验支撑。本项目研究不仅在拓展高核币金属簇合物的种类与功能等方面具有重要意义，为解释没有晶体结构的币金属团簇的稳定性、结构以及结构-性能关系提供参考与模型，而且为检测生活用品中重金属离子污染程度提供新材料与新方法。

英文摘要： The high-nuclearity coinage-metal clusters are important for the applications in catalysis, sensor and medical therapy because of their unique components and electronic structures. We are going to employ the organic ligands (including thiols, alkynyls, and phosphines) reacting with coinage-metal through the methods of solution evaporation, hydrothermal/solvothermal, ionic liquid heating and microwave heating, to construct a series of high-nuclearity homometallic/heterometallic coinage-metal clusters in the presence of different templates. And then their crystal structures and luminescent properties will be characterized. Some of them will be made into the coinage-metal nanoclusters which act as the sensors for the heavy metal ions (including Hg(II), Cr(III), Cd(II), Pb(II) etc.). And then the mechanism will be figured out. In addition, we will investigate the rules of syntheses and self-assembly, structure features, relations between structures and properties of the high-nuclearity homometallic/heterometallic coinage-metal clusters, forming a basis for further design and synthesis of molecular devices based on the high-nuclearity homometallic/heterometallic coinage-metal clusters with optical sensor properties. In conclusion, this project expands the structures and properties of the high-nuclearity homometallic/heterometallic coinage-metal clusters, and offers the examples to explain the stability, structure and relation between structure and property of the coinage-metal nanoclusters without crystal structures. Furthermore, it provides some novel materials and synthesis method to obtain some new sensors for the heavy metal ions.
