Abstract: | γ-cyclodextrin (γ-CD) inclusion complex containing 2-mercaptobenzothiazole (MBT) or 2-mercaptobenzimidazole (MBI) as guest was prepared by precipitation method at two conditions (at room temperature and under sonic energy). Supramolecular nanocontainers were characterized by 1H-NMR, XRD, SEM, DSC and FTIR, which proves the formation of the inclusion complex where the benzyl part of MBT or MBI has been encapsulated by the hydrophobic cavity of γ-CD. Differences between 1H-NMR, FTIR and XRD spectra of physical mixtures and inclusion complex indicated formation of MBT/γ-CD and MBI/γ-CD supramolecular nanocontainers in solid phase. |
