Blue Phase Mixtures of Bent-Core Liquid Crystals and Chiral Dopants

ORAL

Abstract

Stable blue phase materials are made using nematogenic bent-core liquid crystals doped with a high twisting power chiral material. Studies show the existence of stable BPIII (blue fog) phase in a relatively wide 10-20\r{ }C temperature range. Polarizing optical microscopy, optical rotation and electro-optical studies were used to characterize the material.
