Thermal behaviour of bambus[6]uril and its chloride caviplex

The present paper presents the thermal behaviour of methyl-bambus[6]uril in its anion-free and chlorine-included form. Our study was based on thermogravimetry associated to Fourier-transform infrared spectroscopy and differential scanning calorimetry. The compounds decompose after 300 ∘ C and both f...

Zusammenfassung:The present paper presents the thermal behaviour of methyl-bambus[6]uril in its anion-free and chlorine-included form. Our study was based on thermogravimetry associated to Fourier-transform infrared spectroscopy and differential scanning calorimetry. The compounds decompose after 300 ∘ C and both forms of this macrocycle, contain four hydration water molecules. The main decomposition products are H 2 O , CO 2 , NH 3 and isocyanic acid as we could detect by FTIR spectroscopy. Finally, we verified that the caviplex loses its chloride ion after 270 ∘ C and may produce the anion-free macrocyle upon heating.
