| Abstract: | In order to study the difference in microscopic orientation of ferro- and antiferroelectric liquid crystalline molecules, we synthesized the partially deuteriated chiral compounds, (S)-(-)-2-methylbutyl 4-(4-(d13)-hexyloxy- and (S)-(-)-2-methylbutyl 4-(4-(d17)-octyloxy-phenyl)benzoates. Fundamental physical properties such as phase transition temperatures, spontaneous polarization and tilt angle were determined. Polarized FTIR measurements were also made to provide information on molecular structure and orientation. |
