Abstract:The first observation of photorefiactivity in ferroelectric liquid crystals (flcs) is reported. The flcs are doped with the easily oxidized chromophore perylene, which also functions as the sensitizer.The electron acceptor di-butylpyromellitirnide is added to induce photoconductivity through an efficient intermolecular electron transfer reaction to produce mobile ions. A strong dependence on the orientation of the wavevector of the optical intefierence pattern and polarization of the writing beams relative to … Show more
