A ferroelectric induction strategy for a zero-dimensional lead-free hybrid material based on chemical modification
Qiao-Lin Li, Wen Zhou, Yi Wu, Xi-Xi Wang, Chun Yang, Jing Wei, Yu-Hui Tan, Yun-Zhi Tang, Heng-Yun YeA zero-dimensional organic–inorganic material [C 5 H 8 NS] 2 [BiI 6 ] ( 1 ) was prepared. By chemically modifying and disrupting its symmetrical structure, [C 4 H 8 N 2 S] 4 [BiI 6 ][Bi 2 I 11 ]I 2 ( 2 ) was obtained, and ferroelectricity was achieved.
