Discovery of ferroelectricity and antiferroelectricity in imidazoles, building blocks in biological system such as vitamin B12

December 27, 2012


Benzimidazoles exhibit above-room-temperature ferroelectricity and antiferroelectricity with a high electric polarization. The discovery in members of a ubiquitous family of organic molecules reveals the possibility of novel low-cost electronic applications of lead- and rare-metal-free ferroelectrics.
