ポリマーテンプレートにより安定化されたアモルファスブルー相の相転移挙動と電気光学特性

We prepared an amorphous blue phase (BPIII) material consisting of a nematic mixture, a chiral compound, a binary monomer mixture and a photo-initiator. The BPIII material was photopolymerized, and the remaining liquid crystal was removed to create a porous cast. By refilling the cast with the achiral nematic mixture, we obtained a polymer-templated BPIII (TN–BPIII). The temperature range of BPIII was extended to more than 80 K. The Iso–BPIII transition temperature was found to depend on Iso–N temperature for the used achiral nematic mixture. We compare electro-optical properties of the TN–BPIII to those of the corresponding polymer-stabilized BPIII (PS–BPIII).
