  Synthesis and Thermally Enhanced Photoinduced Orientation of Liquid Crystalline Polymer Possessing Vinyl End Group

  摘要：

  Methacrylate polymer liquid crystals containing p-substituted 4-cinnamoyloxybiphenyl (CB) side group were synthesized. Two vinyl end groups were introduced to investigate the influence of the end group on the photoinduced reorientation behavior. Thermally enhanced photoinduced orientation of polymer thin films was performed by irradiating with linearly polarized ultraviolet (LPUV) light and annealing. The reorientation behavior was evaluated by measuring the polarization absorption spectroscopy. When the degree of the photoreaction was around 10 mol%, the reorientation direction was parallel to the polarization of LPUV light for both polymer films. On the other hand, when the degree of the photoreaction was low, out-of-plane orientation was observed for the polymer with the longer end group.

• Thermal Behaviour and Mesophase Structure of Cyclic Oligosiloxanes With Chiral Mesogenic Groups
  作者：Joanna Sołtysiak、Ewa Białecka-Florjańczyk、Ewa Kowalczyk、Jan Przedmojski

  日期：2004.1

  Chiral, smectogenic pendant groups have been covalently attached to cyclic oligosiloxanes by hydrosilylation. Differential scanning calorimetry, optical polarising microscopy, and X-ray diffraction measurements reveal liquid crystalline properties for all synthesized monomers and oligomers. The monomers, which differ by the nature of the rigid mesogenic core or end groups, showed enantiotropic smectic A phases. Almost all of cyclic oligosiloxanes present chiral smectic C phases. The mesomorphic range of these oligomers is greatly enhanced relative to the type of monomers and the ring size as well.
