英文摘要
Realization of ferroelectric columnar liquid crystal phases were attempted by modification of the molecular structures of liquid crystalline urea compounds. The polar structure of the column was clarified by the effect of alkyl chain length of the urea compounds. Lowering of the liquid crystal temperature range and improvement of the response time on applying a triangular wave voltage were observed in the liquid crystal phases. Further, it was found that the oxygen atoms in the arms of the urea molecules are necessary for the polar switching.
