single-site ammonium thread enhances the binding strength between the DB24C8 ring and the ammonium thread. Investigations carried out between the double-site ammonium thread and DB24C8 reveal that the relative amount between the [2]pseudorotaxane and the [3]pseudorotaxane can be controlled by changing the ratio between the double-site ammonium thread and DB24C8. Quantitative studies carried out by NMR
