By using a diamond anvil cell the trans, trans-Dibenzylideneacetone molecular crystal was studied with high pressure Raman, fluorescence spectroscopy and EDXRD at room temperature. A crystalline to crystalline phase transition is found at 1.0~1.3 GPa; meanwhile, a pressure induced chemical reaction is observed and the reaction is completed around 6.5 GPa. The EDXRD spectra show that a new covalent bond produces in this chemcial reaction process. The possible chemical reaction paths are suggested as the openning of C=C bond of the molecule and then combination between adjacent molecules. Another crystalline to crystalline phase transition forms around 11 GPa. After the pressure is released, the newly formed phase of material can remain stable at ambient conditions.

利用金刚石对顶砧(DAC)高压装置在室温下对反式联苯乙烯酮(Trans,Trans-Dibenzylideneacetone)分子晶体进行了高压拉曼谱、荧光光谱和能量色散X射线衍射(EDXRD)研究。结果表明,在压力为1.0~1.3 GPa时,反式联苯乙烯酮发生了晶体—晶体的结构相变,同时开始伴随有压力诱导的化学反应,反应完成的压力为6.5 GPa。高压X射线研究表明,这次相变有新的共价键产生,可能的化学变化过程是,C=C双键打开再与相邻的分子结合生成新的共价键。在压力大约为11 GPa时,反式联苯乙烯酮分子晶体再次发生了晶体的结构相变。新产生的物质在卸压后依然保持稳定。

利用金刚石对顶砧(DAC)高压装置在室温下对反式联苯乙烯酮(Trans,Trans-Dibenzylideneacetone)分子晶体进行了高压拉曼谱、荧光光谱和能量色散X射线衍射(EDXRD)研究。结果表明,在压力为1.0~1.3 GPa时,反式联苯乙烯酮发生了晶体—晶体的结构相变,同时开始伴随有压力诱导的化学反应,反应完成的压力为6.5 GPa。高压X射线研究表明,这次相变有新的共价键产生,可能的化学变化过程是,C=C双键打开再与相邻的分子结合生成新的共价键。在压力大约为11 GPa时,反式联苯乙烯酮分子晶体再次发生了晶体的结构相变。新产生的物质在卸压后依然保持稳定。

By using a diamond anvil cell the trans, trans-Dibenzylideneacetone molecular crystal was studied with high pressure Raman, fluorescence spectroscopy and EDXRD at room temperature. A crystalline to crystalline phase transition is found at 1.0~1.3 GPa; meanwhile, a pressure induced chemical reaction is observed and the reaction is completed around 6.5 GPa. The EDXRD spectra show that a new covalent bond produces in this chemcial reaction process. The possible chemical reaction paths are suggested as the openning of C=C bond of the molecule and then combination between adjacent molecules. Another crystalline to crystalline phase transition forms around 11 GPa. After the pressure is released, the newly formed phase of material can remain stable at ambient conditions.
