Cyclodextrin-based rotaxanes for polymer materials: challenge on simultaneous realization of inexpensive production and defined structures

Beilstein Journal of Organic Chemistry
Owing to their dynamic natures, rotaxane-based polymers are attractive motifs for developing stimuli-responsive materials. However, the accurate control of the rotaxane structure, which can be achieved via multistep synthesis, is key to utilizing the ...

Azo‐Dye Rotaxanes

Angewandte Chemie International Edition in English, 1997
The hydrophobic effect was used to assemble encapsulated azo dyes such as 1 in water. The dumbbell-shaped dyes were synthesized inside α-cyclodextrin, β-cyclodextrin, or a cyclophane to yield stable rotaxanes.
