The First [5]Supercyclodextrin Whose Cyclopentameric Array Is Held Only by a Mechanical Bond.

The first [5]supercyclodextrin 1s whose nano-sized cyclopentameric array is held only by a mechanical bond was synthesized by the pentakis-azo coupling of a new hermaphrodite monomer 2 with 2-naphthol as a stopper, isolated by chromatography, and characterized by MS, 2D NMR, and vis spectral methods with the help of computer simulation.
