PB19 Stabilization of blue phases by spatial arrangement of chiral mesogens

Abstract

To investigate the influence of molecular structure of dopants for stabilization of blue phases, we prepared dopant compounds which had different spatial arrangements of chiral mesogens, and they were added to 5CB, respectively. The mixture of 5CB with a tripodant compound showed the widest temperature range of the blue phase in this series, and compounds possessing two mesogens at o-, m- and p- positions of benzenes indicated a clear difference in the temperature range of the blue phase. We suggested the mechanism for stabilization of the blue phases.
