我们在本文中描述了基于三蝶烯的表面活性剂的合成，该表面活性剂设计成具有通过非共价相互作用在水中溶解单壁碳纳米管（SWNT）和C（60）的能力。此外，还制备了一种对单壁碳纳米管和C（60）具有相同增溶能力的两亲性萘基表面活性剂。合成的化合物被设计成具有两个离子或非离子尾部，以确保与溶剂的大量超分子相互作用，从而促进强增溶。表面活性剂产生稳定的悬浮液中的单壁碳纳米管分散和表面活性剂/单壁碳纳米管复合物形成的是稳定的超过一年。采用紫外/维斯/近红外吸收光谱、透射电子显微镜和原子力显微镜来探测表面活性剂和单壁碳纳米管在水中分散体的增溶性能。
We describe herein the synthesis of a triptycene-based surfactant designed with the ability to solubilise single-walled carbon nanotubes (SWNTs) and C(60) in water through non-covalent interactions. Furthermore, an amphiphilic naphthalene-based surfactant with the same ability to solubilise SWNTs and C(60) has also been prepared. The compounds synthesised were designed with either two ionic or non-ionic tails to ensure a large number of supramolecular interactions with the solvent, thereby promoting strong solubilisation. The surfactants produced stable suspensions in which the SWNTs are dispersed and the surfactant/SWNT complexes formed are stable for more than one year. UV/Vis/NIR absorption spectroscopy, TEM and AFM were employed to probe the solubilisation properties of the dispersion of surfactants and SWNTs in water.
