Abstract

Polymer stabilized blue phase liquid crystals (PS-BPLC) have attracted a considerable amount of attention because of their application to information display and photonic technology. PS-BPLC exhibit several attractive features

such as reasonably wide temperature range

sub-millisecond gray-to-gray response time

no need for alignment layer

and optically isotropic voltage-off state. After reviewing recent progress in monomers stabilizing blue phases

we describe their electro-optical performance. Molecular structure of monomers

the concentration of monomers

use of cross-linker and their influence on PS-BPLC were the main topics of this review. A more detailed discussion was emphasized on the influence of varied structure in the monomers including the introduction of fluorine atoms

chiral center and methylation of end-alkene. Furthermore

some advanced concepts in material design for PS-BPLC were presented.
