conductivities of the single crystals were measured in a wide temperature range. The results of these three compounds were shown at different temperatures. Referring to the crystal structure, the water molecules are confined in a local position and the protons cannot spread freely over the whole crystal lattice. In this way, the information from X-ray analyzed crystal structure allowed us to predict
新化合物带有一个(N-(2-(1H-咪唑-4-基)乙基)苯甲酰胺; A1)和两个(N,N'-双(2-(1H-咪唑-5-基)乙基)对苯二甲酰胺; A2)和三个(N,N',N''-三(2-(1H-咪唑-5-基)乙基)苯-1,3,5-三甲酰胺; A3)合成组胺单元,期望在存在咪唑基团的情况下在高温区域实现高质子传导性。X射线晶体结构分析揭示了强大的分子内和分子间氢键的网络结构。热降解温度远高于原始组胺的温度。在较宽的温度范围内测量了单晶的质子电导率。在不同温度下显示了这三种化合物的结果。关于晶体结构,水分子被限制在局部位置,并且质子不能在整个晶格上自由扩散。这样,
