STUDY ON CHIRAL LIQUID CRYSTALLINE POLYMERS WITH BIPHENYLENE AND AZOBENZENE AS THE MESOGENS

Chiral liquid crystalline polymers containing biphenylene and azobenzene as the mesogens and S(-)-2- methyl-1-butanol as the chiral end group were synthesized and characterized by DSC, POM and X-ray diffraction. These polymers show crystalline or glassy liquid crystalline phase at room temperature. Most polymers show smectic A or highly ordered smectic phases above melting temperature.
