| 摘 要： | 本研究合成了化合物二乙胺六氯化锡 [Et2NH2]2+[SnCl6]2- (1)并对其进行了单晶X-射线衍射, DSC以及变温介电性能测试。研究结果表明,化合物1在高于370 K时发生了可逆一级相变,其相变过程与六氯化锡阴离子的各向同性旋转以及二乙胺阳离子的180°翻转运动有关。对应于该相变过程,化合物1可以实现高低介电状态转换,因而有望成为一种新型的高温分子基介电开关材料。

| Abstract: | Diethylammonium hexachlorostannate(IV) [Et2NH2]2+[SnCl6]2- (1) was prepared and characterized by single-crystal X-ray diffraction, elemental analysis, DSC and temperature-dependent dielectric spectroscopy. The results indicated that compound 1 could undergo a reversible first-order phase transition over 370 K. Corresponding to this phase transition, compound 1 was found for the first time to undergo transitions between high and low dielectric states, which indicates a new type of molecule-based material with high-temperature switchable dielectric property. |
