英文摘要 | The inclusion of polymer chains by cyclodextrins (CDs) may generate column-like supramolecules. Herein, we report that the selective threading of cyclodextrin rings onto one segment of a double hydrophilic diblock copolymer in water generates spherical aggregates. Poly(ethylene oxide)-blockpoly((dimethylamino)ethyl methacrylate) (PEO-b-PDMA) may dissolve in water to form a homogeneous solution. However, when alpha-CDs are introduced, they thread onto the PEO segments to form pseudopolyrotaxanes, which tend to aggregate. Instead of forming a precipitate, novel supramolecular particles are generated which are attributed to the stabilization of the soluble PDMA segments. The organization process and the assembly structure were characterized by dynamic fight scattering, X-ray diffraction, electron microscopy and 1D NOE NMR spectra. Such novel particles are biocompatible and could have potential applications as biomedical and stimulus-response materials. |
