Outline of Final Research Achievements

Novel Columnar liquid crystalline compounds in which their polar directions were switchable by applying a voltage were synthesized, and we successfully obtained their polymer sheets which remain their polarities. Though polymerization of the compound possessing Br groups as its terminal groups gave an uneven and opaque brown polymer sheet, that possessing vinyl groups as its terminal groups produced a flat and transparent polymer sheet. Accordingly, the quality of the polymer sheets were highly improved. Furthermore, a SHG (second harmonic generation) microscope by which polarity of liquid crystalline materials can be measured, has been developed, and it made the quantitative and qualitative observation possible.
