Chinese Chemical Letters 2024年第10期35卷 487-490页

作者： Zhi-Yuan yue Hua-Kai Li Na Wang Shan-Shan Liu Le-Ping Miao Heng-Yun Ye Chao shi Chaotic Matter Science Research Center Jiangxi University of Science and Technology

Since the appearance of Rochelle salt, ferroelectrics have received extensive attention from researchers due to they are playing an important role in sensors, memories, mechanical actuation, and so on. In recent years, with the rapid development of molecular ferroelectrics, high-performance molecular ferroelectrics have become effective complement to inorganic ferroelectrics. However, compared with inorganic ferroelectrics, the family of molecular ferroelectrics is relatively scarce, and exploring highperformance ferroelectric materials through new synthesis strategies has become the trend of molecular ferroelectrics. Here, we successfully transformed non-polar material 1（2-H2PCA）2（H2O）CdCl6（2-H2PCA = 2-picolylamine cation） into polar material 2（2-H2PCA）2CdCl6by single-crystal to single-crystal transformation（SCSCT）. Meanwhile, 2 exhibits clear ferroelectricity with a high-temperature Tcof 378 K,a Psof 1.18 μC/cm2at 300 K. This work not only realizes the purpose of synthesizing ferroelectrics by forming polar structures by SCSCT, but also realizes the reversibility of SCSCT, which provides ideas for the construction and exploration of new molecular ferroelectrics.
