中文摘要: 本项目拟研究多种价态金属离子参与的新型两亲分子低维自组装结构的构筑与应用。所采用的两亲分子在电性上有阴离子和阳离子型,分子结构上则有芳香共轭型及Gemini型等。我们将利用这些构筑基元与多种类型金属离子作用进行低维自组装并探寻其规律,实现通过引入金属离子以及改变其他环境因素对自组装体系进行调控。进一步,通过自模板法合成螺旋、纤维、管等功能性低维无机纳米材料及有机-无机杂合材料,以及利用纳米纤维体系的特性制备可重复利用的小尺寸纳米颗粒分离膜。

英文摘要: The project will focus on the construction and application of low-dimensional self-assemblies in mixed systems of multivalent metal ions and novel amphiphiles. Several series of novel cationic and anionic amphiphiles will be designed and synthesized to interact with many multivalent metal ions in order to construct low-dimensional self-assemblies. The effect of molecular structure, metal ion and many environmental factors (such as temperature, pH and light) in the self-assembly process will be systematically studied. On the basis of the research results, regulation and control of the self-assemblies will be realized. Furthermore, varieties of aggregates we obtained will be used as self-templates to synthesize many functional inorganic and organic-inorganic hybrid materials. Besides, other applications of these self-assemblies will also be widely investigated.
