Neutral-ionic transition, ferroelectricity, and field-effect transistors based on molecular donor-acceptor compounds
Versatile pi-electronic functionality enabled by application of molecular donor(D)-acceptor(A) compounds are overviewed. These compounds are highlighted with respect to the quantum neutral-ionic phase transition, relaxor, displacive-type ferroelectricity, and also to the use in interface engineering of organic field-effect transistors (FETs).
