Chemically-Responsive Sol−Gel Transition of Supramolecular Single-Walled Carbon Nanotubes (SWNTs) Hydrogel Made by Hybrids of SWNTs and Cyclodextrins

Abstract

Hybrids of single-walled carbon nanotubes (SWNTs) and β-cyclodextrins (β-CDs) were prepared by π−π interaction between pyrene modified β-CDs and SWNTs. Moreover, chemically responsive supramolecular SWNT hydrogel was constructed using host−guest interactions by means of hybrids of SWNTs and β-CDs.
