2001) Synthesis and characterization of halogen-containing ferroelectric liquid crystals and side chain liquid crystalline polymers, Liquid Crystals, 28:3, 365-374, A new series of ferroelectric liquid crystals and side chain liquid crystalline polymers based on halogen-containing chiral centres has been synthesized. Chemical structures were analysed by NMR. Liquid crystal phases were characterized by diOE erential scanning calorimetry, optical polarizing microscopy, and X-ray diOE ractometry. The behaviour of the liquid crystalline phases was investigated as a function of spacer units and diOE ering terminal asymmetric moieties. It was found that phase transition temperatures decreased with increasing length of the oligooxyethylene spacer unit. DiOE ering terminal asymmetric moieties led to diOE ering mesophase phenomena. Furthermore, a wide temperature range (including room temperature) of a chiral smectic C phase was achieved.
