Abstract

Abstract:

Two new type pseudorotaxanes are formed by novel (-electron-rich aromatic polyethers containing hydroxy and thiohydroxy with cyclobis(paraquatphenylene)tetracationic cyclophane(CPQT) respectively. We use ¹H NMR spectroscopy to study the property of pseudorotaxanes, and found that the pseudorotaxane containing hydroxy is more stable than the pseudorotaxane containing thiohydoxy as a result of ［C-H…OH］hydrogen bonds. Otherwise, we can monitor the pseudorotaxane containing thiohydoxy by Ag⁺⁺.

Key words: NMR, Pseudorotaxane, Superamolecular, NMR Spectroscopy, Cyclophane
