Piezoelectricity in Polar Supramolecular Materials

Martin U. Pralle, Kenji Urayama, Gregory N. Tew, Dieter Neher, Gerhard Wegner, Samuel I. Stupp

Abstract

Units with large effective dipole moments (shown schematically) are suggested to explain the observation of spontaneous piezoelectric behavior in polar self-assembled films comprised of clusters formed by rod-coil molecules. The piezoelectric response of heated films remains upon cooling.
