Abstract

One-dimensional (1D) nanostructures, including polymeric, small molecule and inorganic types, are currently being investigated in great detail for their unique mechanical, optical, electronic properties and potential implementation as devices. To integrate 1D nanostructures into device applications, it is of importance to align such nanostructures in a parallel, scalable, and highly reproducible manner independent of the specific materials. Well aligned 1D nanostructures might exhibit superior properties that are not found in their disordered counterparts, allowing promising applications in diverse fields. This critical review summarizes the recent work in the alignment of polymeric, small molecule and inorganic 1D nanostructures, in particular, the advantages and drawbacks of various aligning approaches. Discussion is focused on an advanced strategy to precisely position each 1D nanostructure by superhydrophobic pillar-structured surfaces. The research prospects and directions of this rapidly developing field are also briefly addressed (123 references).

摘要

一维（1D）纳米结构，包括聚合物、小分子和无机类型，目前正在被深入研究，因其具有独特的机械、光学和电子性能，并有可能作为器件进行应用。为了将 1D 纳米结构集成到器件应用中，以一种与特定材料无关的平行、可扩展和高度可重复的方式对这些纳米结构进行对齐是很重要的。良好对齐的 1D 纳米结构可能表现出在无序对应物中找不到的优越性能，从而在各个领域有很有前景的应用。这篇重要的综述总结了最近在聚合物、小分子和无机 1D 纳米结构的对齐方面的工作，特别是各种对齐方法的优缺点。讨论集中在一种通过超疏水柱状结构表面精确定位每个 1D 纳米结构的先进策略上。还简要地讨论了这个快速发展领域的研究前景和方向（123 篇参考文献）。
