Carbon nanotubes (CNTs) are carbon clusters (polymers) with huge molecular weight and have been the central material in the field of nanomaterials science and nanotechnology because of their remarkable electronic, thermal, mechanical, optical, and electrical properties. In this review article, we first focus on the formation of self-assembled CNT superstructures and spontaneous conductive CNT-honeycomb structure formation from CNT/long-chain ammonium lipids by simple solvent casting. We also summarized our recent studies on specific molecular interactions and recognition at single-walled carbon nanotube surfaces and CNT chirality recognition using specific polymers. For such studies, the key issue is to develop a methodology to solubilize/disperse them in solvent because as-synthesized CNTs form tightly bundled structures as a result of their strong van der Waals interactions and are insoluble in many solvents. For the analysis of molecules and CNT surfaces, the introduction of thermodynamic treatment and an HPLC method using CNT-coated silica as a stationary phase was powerful.
碳纳米管（CNTs）是具有巨大分子量的碳簇（聚合物），由于其显著的电子、热、机械、光学和电学性能，已成为纳米材料科学和纳米技术领域的核心材料。在这篇综述文章中，我们首先关注的是自组装 CNT 超结构的形成，以及通过简单的溶剂浇铸从 CNT/长链铵脂质中自发形成的 CNT 蜂窝状结构。我们还总结了我们最近在使用特定聚合物的单壁碳纳米管表面的特定分子相互作用和识别以及 CNT 手性识别方面的研究。对于这样的研究，关键问题是开发一种将它们溶解/分散在溶剂中的方法，因为合成的 CNT 由于其强范德华相互作用而形成紧密的束状结构，并且不溶于许多溶剂。对于分子和 CNT 表面的分析，热力学处理的引入和使用 CNT 涂覆的硅胶作为固定相的 HPLC 方法是非常有效的。
