The phase transitions of a series of 1-alkyl-1-azoniabicyclo[2.2.2]octane bromides were studied on the basis of DSC, the measurements of the ionic conductivities of the bromide anion, and Raman spectroscopy. Most of the materials exhibited three endothermic signals at Tc1, Tc2, and Tc3 (Tc1
基于差示扫描量热法(DSC)、溴离子电导率的测量以及拉曼光谱技术,研究了一系列1-烷基-1-氮杂双环[2.2.2]辛烷溴化物的相变过程。在加热过程中,大多数材料在Tc1、Tc2和Tc3(Tc1
