Electroresistance and electro-optic effects in molecular ferroelectrics

Molecular ferroelectrics are often considered as an alternative to inorganic ferroelectrics due to their structural diversity, optical transparency, and low-temperature solution processing. A significant amount of molecular ferroelectrics have been developed and studied for their fundamental mechanisms and potential applications in electronic devices. This review will report the recent findings in the study of electroresistance and electro-optic effects based on molecular ferroelectrics. Different varieties of molecular ferroelectrics are discussed according to their electronic structure and related electroresistance and electro-optic effects. We sketch the current theoretical understanding of electroresistance and electro-optic effects in molecular ferroelectrics, summarize key experimental results, and outline promising prospects in future molecular electronic devices.
