Grayscale memory effect and flexoelectric property of highly-kinked bent-core liquid crystals

摘要

We investigated the electrooptical properties of a bent-core liquid crystal with a high kink angle. The bent-core liquid crystal showed a bistable memory effect and the memory retention time was over 10 h. A nematic liquid crystal doped with a small amount of bent-core liquid crystal showed flexoelectric anisotropy ～37.5 pC/m much greater than the pure host nematic liquid crystal. We also examined the elastic constant of the bent-core liquid crystal doped nematic mixture vs temperature.
