一般注記This study dealt with the conformational change in cyclodextrin inclusion complexes by treatjng at ultra-high pressure. Menthol, camphor and limonene were employed as guests with different molecular sizes and cyclodextrin was used as a host. The ultra-high pressure, more than 100 MPa, was applied to the inclusion complex in water. After the pressure treatment, guest was released from the cyclodextrin cavity with decreased rate. Infrared spectra were measured for the inclusion complexes after ultra-high pressure treatment. Peak intensity for C-H stretching of methyl group at 2958 and 2870 cm-I decreased relatively to the intensity for C-H stretching of methylene group at 2928 and 2853 cm-I, though no mechanochemical reaction was recognized by 1H-NMR spectroscopy after the pressure treatment. The results show that conformation of inclusion complex changed to reduce the CH3 vibration by treating at ultra-high pressure.
