| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 94 === First, a series of liquid crystal polymers with different amounts of cholesterol mesogens and ferroelectric property are synthesized in this research. The structures of the compound synthesized are confirmed by IR and 1H-NMR spectroscopy. The thermal properties are characterized by DSC, POM (Polarized Optical Microscopy). In this research, the 3-D molecular arrangement of molecular were measured by Polarization Modulation-Attenuated Total Reflection-Flourier Transform Infrared spectroscopy (PM-ATR-FTIR).
Second, we discuss two materials which are cinnamoyl chloride and azobenzene. The cinnamoyl chloride can induce the photo-dimerization reaction under linear-polarized UV light. Similarly, azobenzene can induce the cis-trans photoisomerization under UV light. This research try to investigate the two materials which are chemically bonded to polyimide. The arrangement of the two materials are studied by Polarization Modulation-Attenuated Total Reflection-Flourier Transform Infrared spectroscopy (PM-ATR-FTIR).
