A “cyclodextrin coat” dramatically enhances the stability of an azo dye towards reductive bleaching, oxidative bleaching, and photo‐bleaching as is demonstrated by the rotaxane 1 . This compound is obtained as a single isomer in high yield from the amine‐substituted dye and trichlorotriazine in water in the presence of the cyclodextrin.
