Plastic/ferroelectric molecular crystals: Ferroelectric performance in bulk polycrystalline forms [PDF]
APL Materials, 2021 Plastic crystals are a class of compounds composed of small molecules with globular structures. Plastic crystals exhibit various unique features, most of which arise from the rotator motion and orientational disorder of the constituent molecules.

Optically Induced Ferroelectric Polarization Switching in a Molecular Ferroelectric with Reversible Photoisomerization [PDF]
Advanced Science, 2021 Ferroelectrics usually exhibit temperature‐triggered structural changes, which play crucial roles in controlling their physical properties. However, although light is very striking as a non‐contact, non‐destructive, and remotely controlled external ...

A 3D-printed molecular ferroelectric metamaterial [PDF]
Proceedings of the National Academy of Sciences, 2020 Significance Molecular ferroelectrics, which show the ability to switch the electromechanical activity by an external electric field, establish the basis for mechanical metamaterial technologies. Despite their theoretical promise, such mechanical metamaterials remain hindered by the lack of adaptive stimuli-responsive materials which ...

Doping induced dielectric anomaly below the Curie temperature in molecular ferroelectric diisopropylammonium bromide [PDF]
Royal Society Open Science, 2018 A dielectric anomaly induced by doping has been observed at about 340 K in chlorine-doped diisopropylammonium bromide. The dielectric anomaly has a switchable behaviour, which indicates potential applications on switches and sensors.

Recipes for improper ferroelectricity in molecular perovskites [PDF]
Nature Communications, 2018 AbstractThe central goal of crystal engineering is to control material function via rational design of structure. A particularly successful realisation of this paradigm is hybrid improper ferroelectricity in layered perovskite materials, where layering and cooperative octahedral tilts combine to break inversion symmetry.
