| Abstract
| - Single-C60-end-capped poly(ethylene oxide) (FPEO) forms a stoichiometric inclusion complexwith α-cyclodextrin in high yield. The complex was characterized by XRD, 13C CP/MAS NMR, 1H NMR,DSC, and TGA. The incorporation of C60 results in no apparent change in the crystal structure. No complexforms between FPEO and β-cyclodextrin. γ-Cyclodextrin (γ-CD) and FPEO form a thermoreversible gelin aqueous solution instead of a stoichiometric crystalline complex, whereas uncapped polymers formcrystalline inclusion complexes with γ-CD in high yields. Interestingly, in a γ-CD/FPEO/PEO aqueoussolution, two PEO chains are able to “recognize” each other and thread through the γ-CD cavity to forma γ-CD/PEO inclusion complex.
