- Abstract: Dipolar 2, 3‐difluorobenzene units are introduced into the backbone of a poly( para ‐phenyleneethynylene) (PPE) to generate a ferroelectric conjugated polymer. The structural features of the partially fluorinated PPE allow for the generation of a remanent polarization in the solid state; the difluorinated benzene rings behave as molecular rotors at high temperature, while at room temperature, stacking of such rings clamps down the ring orientation. The molecular dipoles can still be oriented by moderate external electrical fields at room temperature, and this PPE is then ferroelectric. The concept should be transferable to other poly(aryleneethynylene)s, and novel conjugated ferroelectric conjugated polymers will be accessible using this concept. Abstract : Polarisierte Polymere : Dipolare 2, 3‐Difluorbenzol‐Einheiten wurden in ein PPE‐Rückgrat eingeführt. Die Difluorbenzolringe wirken bei hohen Temperaturen wie molekulare Rotoren, während sie sich bei Raumtemperatur in einer Weise stapeln, dass eine remanente Polarisation resultiert. Die Moleküldipole lassen sich durch mäßig starke externe elektrische Felder ausrichten. Somit ist dieses PPE ein ferroelektrisches konjugiertes Polymer.
