Chemically-responsive sol-gel transition of supramolecular single-walled carbon nanotubes (SWNTs) hydrogel made by hybrids of SWNTs and cyclodextrins

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