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.

TL;DR: This review summarizes recent developments in molecular ferroelectrics since 2011 and focuses on the relationship between symmetry breaking and ferroelectricity, offering ideas for exploring high-performance molecular ferryelectrics.

TL;DR: In this paper, a mononuclear metal-organic compound, [Cu(Hdabco)(H2O)Cl3] (1, dabco = 1,4-diazabicyclo[2.2] octane) in which the CuII cation adopts a slightly distorted bipyramidal geometry where the three Cl anions constitute the equatorial plane and the Hdabo cation and H2O molecule occupy the two axial positions, was synthesized.

TL;DR: Imidazolium periodate (IPI) is found to be an improper ferroelectric that shows bistable properties simultaneously in three channels of dielectricity, piezoelectricities, and second-harmonic generation within the temperature window 300-310 K.

TL;DR: Temperature-dependent solid-state nuclear magnetic resonance measurements reveal three kinds of molecular motions existing in the compound: pendulumlike swing of 4-methoxyanilinium cation, rotation of 18-crown-6 ring, and rotation of the methoxyl group, which corresponds to the centrosymmetric-to-noncentrosy mmetric arrangement of the compound, resulting in the formation of ferroelectricity.
