中文摘要: 核/壳结构的纳米复合材料由于其内部分别富集不同的成分,显示出特殊的双层或多层结构,通过核与壳的功能复合与互补,调制出有别于核或壳本身性能的新型功能材料,为新材料的设计提供了非常便捷的途径,是当前材料科学研究的热点之一。当前,核/壳结构主要集中在无机材料包覆无机纳米粒子或用聚合物来修饰无机纳米粒子。在成功合成系列稀土羧酸配位聚合物纳米材料的基础上,本研究拟以其核/壳(核和壳均为配位聚合物)结构为研究对象,尝试其核/壳结构的合成,以期获得一些具有新颖结构和性能的新材料,拓展材料的种类。测试其光学性能,对核壳之间的相互作用及其作用机理进行研究,找出壳的厚度以及种类等对材料光学性能的影响和规律,对其应用进行探索。不仅可能获得系列新型复合纳米材料,还可为其它配位聚合物核/壳纳米结构的合成提供理论和实验依据,是一项非常值得研究的工作。

英文摘要: Owing to the core/shell structured nanocomposites have multicomponents, they give properties which are different from their core or shell, which provides a facil way to the design of new materials and have been intensively studied.To date, most of the studies are concentrated on the fabrication of inorganic nanoparticles coated with inorganic shell or polymer shell. On the basis of successful preparation of rare earth carboxylic coordination polymer nanostructures, this project aims to prepare their core/shell structured nanocomposite (both core and shell are coordination polymer). Their photoluminescence properties will be invesitigated and the effects of the kind and thickness of the shell on the properties will be explored, and the interaction rule between the core and shell will be studied. Furthermore, their promising applications will be explored. It may give theorectical and experimental instructions for the preparation of the other coordination polymer core/shell nanostructures, which if of significant importance.
