在本次通讯中，我们描述了在携带芘的铵离子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-可见吸收、荧光和 H-1 NMR 光谱对其进行了表征。我们展示了水分散体/溶液中纳米管侧壁和芘部分相互作用的证据。
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 I gave a transparent dispersion/solution of the nanotubes, which was characterized by transmission electron microscopy, UV-vis absorption, fluorescence and H-1 NMR spectroscopies. We showed evidence for the interaction of the nanotube sidewall and the pyrene moiety in the aqueous dispersion/solution.
