Abstract
Organic–inorganic hybrid ferroelastic materials have emerged as promising candidates for various applications such as mechanical switches, signal conversions, and memory materials because of their convenient processing, structural flexibility, and environmental friendliness. Here, we reported a supramolecular assembly hybrid perovskite (15-crown-5·NH4)2TeCl6 (1) semiconductor containing stator ammonium and rotor 15-crown-5 as cations and TeCl6 as an anionic part. This hybrid perovskite shows a ferroelastic phase transition and dielectric switch induced by the motions of the crown rotor. In addition, it shows an X-ray detection response with a clear switching ratio of photocurrent 0.011 and dark current 0.001 nA cm–2. This study reveals the advantages of a supramolecular rotor strategy in discovering novel molecular ferroelastic semiconductor materials and provides a new avenue to explore functional hybrid molecular materials.
有机-无机杂化铁弹性材料因其加工方便、结构灵活和环境友好等优点,已成为机械开关、信号转换和记忆材料等各种应用的有前途的候选材料。在此,我们报道了一种超分子组装混合包晶(15-crown-5-NH4)2TeCl6 (1)半导体,其定子铵和转子 15-crown-5 为阳离子,TeCl6 为阴离子。这种混合包晶石显示了铁弹性相变和由冠转子运动诱导的介电转换。此外,它还具有 X 射线探测响应,光电流 0.011 nA cm-2 和暗电流 0.001 nA cm-2 的开关比非常明显。这项研究揭示了超分子转子策略在发现新型分子铁弹性半导体材料方面的优势,并为探索功能性混合分子材料提供了一条新途径。
