  Water-Soluble Single-Walled Carbon Nanotubes via Noncovalent Sidewall-Functionalization with a Pyrene-Carrying Ammonium Ion

  摘要：

  在这篇论文中，我们描述了以下发现：在含芘铵离子1的水溶液中，对固体单壁碳纳米管（p-SWNT）进行超声处理，得到透明的纳米管分散体/溶液，并通过透射电子显微镜、紫外-可见光吸收、荧光和1H NMR光谱对其进行了表征。我们证明了纳米管侧壁与水分散体/溶液中的芘部分之间的相互作用。

  In this communication, we describe the finding that sonication of solid single-walled carbon nanotubes (p-SWNT) in an aqueous solution of a pyrene-carrying ammonium ion 1 gave a transparent dispersion/solution of the nanotubes, which was characterized by transmission electron microscopy, UV-vis absorption, fluorescence and 1H NMR spectroscopies. We showed evidence for the interaction of the nanotube sidewall and the pyrene moiety in the aqueous dispersion/solution.

• Solubilization of Single-Walled Carbon Nanotubes by using Polycyclic Aromatic Ammonium Amphiphiles in Water—Strategy for the Design of High-Performance Solubilizers

  We describe the design of polycyclic aromatic compounds with high performance that dissolve single-walled carbon nanotubes (SWNTs). Synthetic amphiphiles trimethyl-(2-oxo-2-phenylethyl)-ammonium bromide (1) and trimethyl-(2-naphthalen-2-yl-2-oxo-ethyl)-ammonium bromide (2) carrying a phenyl or a naphtyl moiety were not able to dissolve/disperse SWNTs in water. By contrast, trimethyl-(2-oxo-2-phena

  我们描述了可溶解单壁碳纳米管（SWNTs）的高性能多环芳族化合物的设计。带有苯基或萘基部分的合成两亲物三甲基-（2-氧代-2-苯基乙基）-溴化铵（1）和三甲基-（2-萘-2-基-2-氧代乙基）溴化铵（2）无法将SWNT溶解/分散在水中。相比之下，虽然增溶能力比三甲基-（2-氧代-2-py-2-py-1）低，但是三甲基-（2-氧代-2-菲咯啉-9-基乙基）-溴化铵（3）增溶了SWNT。 -基-乙基）-溴化铵（4）（在参考文献4a中简要描述了使用4观察到的增溶行为）。利用透射电子显微镜（TEM）以及可见/近红外，荧光和近红外光致发光光谱法揭示了4在水中的增溶特性，并将这些结果与使用十二烷基硫酸钠（SDS）和十六烷基三甲基溴化铵（HTAB）作为增溶剂得到的结果进行比较。化合物4在温和的实验条件下溶解了所产生的SWNT（原始SWNT）和纯化的SWNT，其溶解能力优于SDS和HTAB。近红外光致发光
