The polypseudorotaxane was characterized by spectroscopic techniques (1H, 13C NMR and FT-IR) and matrix assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS). The experimental results reveal that this polypseudorotaxane behaves as a pH-driven polymeric switch. Thus, when amine groups are protonated at an appropriate pH, CB6s are located on the triazole rings due to ion-dipole interaction, whereas at high pH they move onto the hydrophobic aliphatic spacer rather than slipping off the polypseudorotaxane. © The Royal Society of Chemistry 2006.EnglishAddition reactionsDesorptionFourier transform infrared spectroscopyHydrophobicityNuclear magnetic resonance spectroscopySynthesis (chemical)Dialkyne monomersDiazidePolypseudorotaxaneOrganic compoundsArticle10.1039/b605057c
