Diisopropylammonium Bromide Is a High-Temperature Molecular Ferroelectric Crystal
Da Wei Fu,Hong-Ling Cai,Yuanming Liu,Qiong Ye,Wen Zhang,Yi Zhang,Xue Yuan Chen,Gianluca Giovannetti,Massimo Capone,Jiangyu Li,Ren-Gen Xiong +10 more
TL;DR: DIPAB is a molecular alternative to perovskite ferroelectrics and ferroelectric polymers in sensing, actuation, data storage, electro-optics, and molecular or flexible electronics and exhibits good piezoelectric response and well-defined ferro electric domains.
Journal ArticleDOI
Diisopropylammonium Chloride: A Ferroelectric Organic Salt with a High Phase Transition Temperature and Practical Utilization Level of Spontaneous Polarization
TL;DR: A simple organic salt, diisopropylammonium chloride, shows the highest ferroelectric phase transition temperature among molecule-based ferroelectrics with a large spontaneous polarization, making it a candidate for practical technological applications.
Journal ArticleDOI
Metal–organic complex ferroelectrics
TL;DR: This tutorial review shows the recent development of the MOC ferroelectrics with particular emphases on the mechanism of ferroelectric-to-paraelectric phase transition, symmetry consideration, and multifunctionality.
Journal ArticleDOI
Tunable and switchable dielectric constant in an amphidynamic crystal.
Wen Zhang,Heng-Yun Ye,Robert Graf,Hans Wolfgang Spiess,Yefeng Yao,Run-Qiang Zhu,Ren-Gen Xiong +6 more
TL;DR: Crystal structure and solid-state NMR studies reveal a switchable property between low and high dielectric states around 245 K, which originates from an order-disorder phase transition of the system, changing the dynamics of the polar dimethylammonium cation.
