摘要：
Noncovalent functionalization of carbon nanotubes (CNTs) can not only preserve their unique properties, but also improve their solubility in aqueous solutions. Herein, two water-soluble sugar-functionalized triptycene derivatives were synthesized and interacted with single-walled carbon nanotubes (SWCNTs) to form stable homogeneous aqueous solutions, which indicated the development of a successful approach to disperse SWCNTs in water. The supramolecular systems formed between triptycene derivatives and SWCNTs are fully characterized through absorption, fluorescence as well as Raman spectroscopy. Moreover, the shape-fitted triptycene-based system also shows selectivity for SWCNTs with certain diameters.
