TL;DR: Trimethylchloromethyl ammonium trichloromanganese(II), an organic-inorganic perovskite ferroelectric crystal processed from aqueous solution, has a large d33 of 185 picocoulombs per newton and a high phase-transition temperature of 406 kelvin (K) (16 K above that of BTO), which makes it a competitive candidate for medical, micromechanical, and biomechanical applications.

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.

TL;DR: A hybrid molecular ferroElectric, (pyrrolidinium)MnCl3, is reported, which exhibits excellent ferroelectricity with a saturation polarization of 5.5 μC/cm(2) as well as intense red luminescence with high quantum yield of 56% under a UV excitation, which may extend the application of organic-inorganic hybrid compounds to the field of ferro electric luminescent and/or multifunctional devices.

TL;DR: The supramolecular bola-like ferroelectric is distinct from the precedent ferroelectrics and will open a new avenue for the design of polar functional materials.
