Novel guest-host liquid crystal systems containing 3,3-disubstituted azobenzenes as guests were prepared on the basis of molecular design by molecular calculations to achieve the improvement of compatibility of the chromophore with nematic phases. No phase change of nematic liquid crystals was induced by the E-to-Z photoisomerization of the guests even at doped concentrations as high as 20 wt%.
基于分子计算的分子设计,制备了含有3,3-二取代
偶氮苯作为客体的新型客体-宿主液晶系统,以改善
染料与向列相的相容性。即使在掺杂浓度高达20 wt%时,客体的E-Z光异构化也未引起向列液晶的相变。
