Abstract

In this paper, we investigated effects of stabilizing blue phase liquid crystal using only reactive chiral dopant, without any other monomers and photoinitiators. First, photo-inactive chiral dopants with high helical twist power (∼166μm^-1) synthesized by us are doped into host nematic LC to induce blue phase and then, the photo-reactive chiral dopant is added to stabilize double twist cylinder. After UV irradiation, BP temperature range is clearly extended compared with pure BP mixture and hysteresis in V-T curve is also dramatically decreased.
