A Supramolecular Ferroelectric With Two Sublattices and Polarization Dependent Conductivity
Advanced Science, EarlyView.Ferroelectric behavior in a supramolecular material with two, independently switchable, sublattices is demonstrated. The sublattices can be associated with the two dipolar groups in the compound. Moreover, the polarization is found to couple to the charge transport in the material, giving rise to a switchable, directional conductivity.
