Single-component organic molecular ferroelectrics based on disk- or wheel-like rotation

Abstract

Large polarizations and their reversible switching, which are indispensable for many functional ferroelectric applications, are achieved in new single-component organic molecular ferroelectrics with rotating strongly dipolar molecules or substituents. In...

Ferroelectricity in organic materials: from materials characteristics tode novodesign

“…The disordering of the polar molecules triggers the phase transition above T c , which refers to an order-disorder type phase transition. 101,102 Under the external electric field, due to the rotational degree of freedom, the orientation of molecular dipoles is reorganised when the direction of the electric field has switched (Fig. 4(a) and (b)).…”
