Metal–organic complex ferroelectrics

Abstract

Ferroelectric materials are of importance and interest in both fundamental scientific research and various technological applications. Metal–organic complexes (MOCs) represent a class of molecule-based ferroelectrics, which have shown various properties or functionalities due to their hybrid inorganic–organic nature. 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.
