A facile approach toward multicolor polymers: Supramolecular self-assembly via host-guest interaction

A one-step and facile strategy toward the construction of multicolor polymers via supramolecular self-assembly was proposed. Multicolor polymers were simply prepared by the self-assembly of adamantane-labeled fluorescein, adamantane-labeled rhodamine B and beta-cyclodextrin polymers via host-guest interaction between P-cyclodextrin and adamantane. Multicolor polymers showed several interesting properties: multiple emission signatures by a single wavelength excitation, easy tunability, intense fluorescence, high photostablility. In addition, the self-assembly approach implied a facile and flexible strategy for constructing functionalized materials, such as multicolor materials for biological labeling and imaging, and sensing materials for the detection of physiological parameters.
