Self-assembly of a water-soluble [2]rotaxane with carbohydrate stoppers

Article abstract of DOI:10.1016/S0040-4039(97)01247-1

A [2]rotaxane self-assembles spontaneously by 'slippage' in D₂O during one week at room temperature when a dumbbell-shaped compound, containing a hydroquinone ring recognition site and terminated by P-D-glucopyranose units, is mixed with cyclobis(paraquat-p-phenylene) tetrachloride. A [2]rotaxane with benzoylated D-glucopyranose residues is obtained when the dumbbell-shaped octabenzoate serves as a template for the formation of the cyclobis(paraquat-p-phenylene) tetracation in DMF.
