【摘要】："自下而上"的纳米结构制备法是一种在原子或分子水平上构筑纳米结构的方法;相比于"自上而下"的蚀刻技术,其可实现更小尺寸的半导体器件的制备。因此,这种"自下而上"制备法将是纳米技术未来的重要发展方向。然而,其中一个存在已久的关键问题是如何实现对所构筑的纳米拓扑结构进行精确控制。此文综述了近期关于如何调控由表面乌尔曼反应合成的纳米材料拓扑结构的研究。其中包括以下三个方面:首先,利用纳米结构与衬底晶格参数之间的匹配关系控制金属有机链的形状;其次,利用超栅格或者超分子模板对长链进行有效剪裁;最后,利用纳米结构与衬底之间对称性的匹配来调控环状和链状产物的形成。另外,我们对寻求普适性模板以调控更广泛类型的纳米材料的拓扑结构进行了展望。
[Abstract]:"bottom-up" nanostructure preparation is a method of building nanostructures at the atomic or molecular level; Compared with "top-down" etching technology, it can achieve the fabrication of smaller semiconductor devices. Therefore, this "bottom-up" method will be an important development direction of nanotechnology in the future. One of the key problems that has existed for a long time is how to control the nanostructures accurately. This paper reviews the recent studies on how to regulate the topological structures of nanomaterials synthesized by surface Ulmann reaction. This includes the following three aspects:. First. The shape of organometallic chains is controlled by the matching relationship between nanostructures and substrate lattice parameters. Secondly, using supergrid or supramolecular template to cut the long chain effectively. Finally, the symmetry matching between nanostructures and substrates is used to regulate the formation of ring and chain products. We look forward to seeking universal templates to regulate the topology of a wider range of nanomaterials.
