可开关导电或介电材料作为关键材料，在现代电子电气设备中具有重要的技术应用，包括数据通信、移相器、变容二极管和光存储等。探索新型可切换导电或介电材料可以显著加速高效电气和电子设备的开发。在此，我们提出了可切换导电和介电材料的第一个实例，其基于开放骨架磷酸盐（C2N2H10）0.5CoPO4。在348 K左右，该开放骨架磷酸盐发生可逆的同构相变，在相变临界温度附近出现电导和电导反常现象。该研究将为寻找新的可开关导电或介电材料以及开放框架磷酸盐的新应用提供路线图。
Switchable conducting or dielectric materials, as the key component, show important technological applications in modern electrical and electronic devices, including data communication, phase shifters, varactors, and rewritable optical data storage. To explore new types of switchable conducting or dielectric materials could significantly accelerate the development of efficient electrical and electronic devices. Herein we present the first example of switchable conducting and dielectric material, which is based on an open-framework phosphate, (C2N2H10)0.5CoPO4. A reversible isostructural phase transition occurs at ∼348 K in this open-framework phosphate, to give both dielectrics and conductance anomaly around the critical temperature of phase transition. This study will provide a roadmap for searching new switchable conducting or dielectric materials as well as new applications of open-framework phosphates.
