Crown Ether Host‐Guest Molecular Ferroelectrics

Chemistry – A European Journal, 2021
AbstractIn recent years, molecular ferroelectrics have received great attention due to their low weight, mechanical flexibility, easy preparation and excellent ferroelectric properties. Among them, crown‐ether‐based molecular ferroelectrics, which are typically composed of the host crown ethers, the guest cations anchored in the crown ethers, and the ...

Recent advances in molecular ferroelectrics

Journal of Physics D: Applied Physics, 2021
Abstract Due to their structural flexibility, tunability and easy processing, molecular ferroelectric materials have emerged to complement the well-known ferroelectric perovskite oxides. A number of compounds have been investigated but, with the exception of polymeric polyvinylidene fluoride, most have not succeeded in achieving their ...

Electronic ferroelectricity in molecular organic crystals

Journal of Physics: Condensed Matter, 2014
Electronic ferroelectricity in molecular organic crystals is reviewed from a theoretical perspective. In particular, we focus on the charge-driven-type electronic ferroelectricity where electronic charge order without inversion symmetry induces a spontaneous electric polarization in quarter-filling systems. Two necessary conditions to realize this type
