合成了两种新型锌基杂化有机无机化合物（AZT）2[ZnX 4]（AZT =氮杂环丁烷阳离子; X = Cl，1; Br，2），作为高温刺激响应材料。系统的热力学表征表明，它们经历可逆的结构相变伴随着可切换的介电常数为342 K为1和356 K为2分别为中心。变温单晶X射线分析和介电常数测量揭示了阳离子和阴离子的有序-无序转变有助于获得所需的电性能。正如预期的那样，晶体结构中的静态-运动转变引起低介电状态和高介电状态之间的介电转变，使它们成为一种可切换的介电材料。
Two new zinc‐based hybrid organic‐inorganic compounds (AZT)2[ZnX4] (AZT = azetidine cation; X = Cl,1; Br,2) were successfully synthesized as high‐temperature stimuli‐responsive materials. Systematic thermodynamic characterization demonstrated that they undergo reversible structural phase transitions accompanied by switchable dielectric constant centered at 342 K for1and 356 K for2, respectively. Variable‐temperature single‐crystal X‐ray analysis and dielectric constant measurements disclosed the order‐disorder transformation of the cation and anion contributed to the desirable electrical properties. As expected, the static‐motional transition in crystal structure arouses dielectric transitions between the low‐ and high‐dielectric states, making them a type of switchable dielectric materials.
