    • Antiferroelectricity in achiral mesogenic mixtures of organic materials 

      Werner, R.; Weyrauch, T.; Navarrete Encina, Patricio; Haase, W.; Soto Bustamante, Eduardo (ELSEVIER SCIENCE BV, 2000-05-12)
      To clarify the mechanism involved in the appearance of antiferroelectric properties in mixtures of polymers containing achiral mesogenic side chains and their monomers, X-ray investigation was carried out in pyroelectrically ...
    • Investigations on new achiral polymeric liquid crystalline mixtures using a pyroelectric modulation technique 

      Navarrete Encina, Patricio; Weyrauch, T.; Soto Bustamante, Eduardo; Werner, R. (GORDON BREACH SCI PUBL LTD, 2000)
      In this paper we report on the synthesis and characterization of new mixtures of achiral liquid crystalline side-chain polymers with their monomers. The samples have a basic structure similar to materials prepared earlier ...
    • SYNTHESIS AND CHARACTERIZATION OF NEW LIQUID-CRYSTALLINE DYES FOR NONLINEAR OPTICS 

      Hanemann, Thomas; Soto Bustamante, Eduardo; Weyrauch, T.; Haase, W. (TAYLOR & FRANCIS LTD, 1993)
      We present the synthesis and a description of the physical properties of several organic dyes containing stilbene as well as azomethine groups. The preparations of all compounds started from a common precursor, ...
