中文摘要: 金属纳米团簇(简称金属团簇),尤其是过渡金属团簇由于其特殊的物理、化学性质,在光电子工业、催化、生物等方面极具应用潜力,近年来备受学界关注;在化学领域,具有多功能耦合性质的材料研究起步较晚,在如磁电、磁光耦合等方面的研究尚不深入。能够通过化学合成的金属团簇恰恰为开展这方面的研究提供了一个理想的物质基础。本项目针对过渡金属团簇多功能化的研究方向,拟通过功能配体分子与团簇前驱体分子的设计与合成技术,利用分子与金属的配位、桥联原理,将金属团簇的化学合成与纳米组装技术相结合,以有机-无机杂化与性质耦合为指导思想,化学合成多功能金属团簇,研究(1)金属原子数、结构、掺杂、配体修饰、化学桥联可控的金属团簇的化学制备、组装和表征,(2)金属团簇结构与性质之间的关系,(3)团簇内与组装团簇的磁、电、光学性质及其耦合。该项目在科学与技术上涉及多学科交叉,其探索研究将为实际应用积累理论与技术储备。

英文摘要: Due to their special physical and chemical properties, metal nanoclusters ('clusters'for short), especially transition metal clusters have great application potentials in the industries of optoelectronics, catalysis and biology. Much academic attention has been cast on its research in recent years. In the field of chemistry, the research of multifunctional materials with coupled properties is lagged compared to that in the physical field. Nowadays, chemical researchers have done a lot of synthesis work on the compounds with multi properties or functions, while the in-depth research on property-coupling such as magnetic-electronics or magnetic-optics coupling is overlooked to some extent. By chemical approaches, the metal clusters can be synthesized, which provides an ideal material basis for the research of the multi functional metal clusters with coupled properties. The program aims the research of multi functionalization of transition metal clusters, with the combination of the functional ligand and precursor molecular design, the coordination and bridge interactions of the metal and ligand, the chemical synthesis of metal clusters and nano-assembly techniques. Using organic-inorganic hybridization and property coupling as the guiding ideology, the program will focus on the synthesis of metal clusters with fun
