Historical Overview of Polar Liquid Crystals
@article{Takezoe2014HistoricalOO, title={Historical Overview of Polar Liquid Crystals}, author={Hideo Takezoe}, journal={Ferroelectrics}, year={2014}, volume={468}, pages={1 - 17} }
Brief history of ferroelectric and antiferroelectric liquid crystals is described. To reduce the symmetry of the molecular systems, two ideas were successfully used; introductions of chirality and molecular shape asymmetry. The chirality introduced into rod-shaped and disc-shaped molecular systems led to chiral smectic C and chiral discotic columnar phases. Dogleg from rod and cone or bowl from disc in molecular shapes brought about polar organization by their packing, realizing so-called…
