| 英文摘要 | In situ crystalization of 1-decyl-3-methylimidazolium tetrafluoroborate ([C10MIM][BF4]) from melt has been investigated under high pressure up to 3.4 GPa at room temperature by using Raman spectroscopy and synchrotron X-ray diffraction measurement. Raman spectral analysis indicated that [C10MIM][BF4] experienced two successive phase transitions at about 0.3 GPa and 1.6 GPa. And the polymorphism was also discussed in view of the conformational isomerism of [C10MIM](+) cation between gauche and trans conformers. Notably, liquid-crystal and crystal-crystal phase transitions were further confirmed by synchrotron X-ray diffraction measurement. Moreover, it also indicated that high structural flexibility of the cations with long alkyl chain might have effect on the degree of disorder of pressure-induced crystallization for ionic liquids.
