液晶/非液晶非対称二量体添加型液晶ブルー相の構造解析と電場応答挙動
Blue phases (BPs) are known to exhibit optical stop bands in a visible range because they have a three-dimensional cubic structure with lattice periods of several 100 nm. Furthermore, since the diffracted wavelength of BPs can be shifted by external electric fields. BPs are expected to be applied for tunable photonic crystals. We have succeeded in expanding a temperature range of BPs from generally ca. 1 o C to 11 o C on heating when an asymmetric dimer with mesogenic-and nonmesogenic-groups was added to BP.
