A Superior Ionic Conducting Plastic Crystal Near Room Temperature with Electrical Bistability and Magnetic Transition
Multifunctional ionic plastic crystals (IPCs) are a class of unique materials that exhibit a wide range of advanced applications. In this work, we proposed a strategy for the design of multifunctional, superior ion-conducting IPCs with bistability in both magnetic and electric properties, moreover, we successfully prepared and thoroughly characterized such an IPC, [PMPyr][Ni(mnt)<sub>2</sub>] (1; PMPyr<sup>+</sup>=N-propyl-N-methylpyrrolidinium, and mnt<sup>2-</sup>=maleonitriledithiolate). Plastic crystal 1 exhibits superior ion conduction near room temperature, and its ion conductivity reaches the order of 10<sup>-2</sup> S cm<sup>-1</sup> at 373 K. Remarkably, the crystal-to-plastic crystal transformation results in 1 simultaneously exhibiting electrical bistability and magnetic transition. Our study paves the way for the development of new IPCs with desirable functional properties.
