Synthesis of a cyclodextrin azo dye [3]rotaxane as a single isomer
Azo coupling between 2,6-dimethylphenol and aqueous 4,4'-bis(diazonio)azobenzene chloride in the presence of α-cyclodextrin yields an azo dye [3]rotaxane as a single stereoisomer, with the 2,3-rims of both cyclodextrins pointing outwards.
