中文摘要： 纳米科学因新型纳米结构的不断发现而获得迅猛发展，自组装形成的纳米结构不仅可以模拟生命体系，而且可用于超分子胶囊、囊泡、多孔蛋白质模拟、离子隧道、分子发射器、有机电子材料等方面的研究，已成为纳米科学发展的前沿。液晶是分子自组装材料的典型范例，其自组装结构的动态可逆可控性是其他自组装体系无法替代的。本项目拟设计合成含苯基噻吩炔（三唑）单元的较长不对称芳香核的棒状分子，两端分别冠以亲酯性烷基卞醚树枝元端基及亲水性寡聚乙氧基链或聚乙二醇卞醚树枝元端基。通过改变刚硬核、亲水部分、亲油部分等结构因素，调控这类分子的自组装结构，从而获得周期有序的正反液晶相系列，着重研究一些特殊的中间相态结构,获取新的复杂自组装液晶超分子纳米材料，本研究发现的自组装规律势必丰富自组装理论，为纳米材料的发展提供新的模型，为材料科学、生命科学的研究奠定基础。

英文摘要： Nanoscience develops rapidly with the discovery of more and more nanostructures. Self-assembled nanostructures can not only simulate life system, but also can be used as supramolecular capsules, vesicles, porous proteins simulation, ion tunnel, molecular transmitter and organic electronic materials, it has become one of the frontiers of nanoscience. Liquid crystal is a typical example of molecular self-assembly system, the dynamic reversible controllability of such self-assembly materials can not be replaced by other self-assembly systems. This project intends to design and synthesis of phenyl-thiophene-acetylene (-triazole) unit contained asymmetric rod-like molecules, capped with alkyl benzyl ether lipophiplic dendron and oligoethyleneoxy chains or benzyl ether hydrophilic dendron on each end of rod core. By changing the molecular structure factors such as rigid core, hydrophilic and lipophilic parts, the molecular self-assembled ability and self-assembly process will be controlled, both the normal and reversed phases will be expected to be obtained. And some special intermediate phases will be obtained too which will be taken as a key research subject. Our study should be contribute to rich the self assembly theory and supply novel models for nanoscience, material science and life science.
