“…[162,170,171] Blue-phase materials are also studied for use in optical lasers. [172] Forthese applications, the narrow temperature range of blue phases was as erious problem. To improve the stability of blue phases,Kikuchi and co-workers added acrylate monomers to the blue-phase liquid crystals and polymerized them.…”

“…Blue phases, which have double chiral nematic structures, were reported to exhibit fast responses, optically isotropic nature, and no requirement for rubbing process for applications of displays . Blue‐phase materials are also studied for use in optical lasers . For these applications, the narrow temperature range of blue phases was a serious problem.…”

Since the discovery of the liquid-crystalline state in 1888, liquid crystal science has made great advances through fusion with various technologies and disciplines. Recently, new molecular design strategies and new self-assembled structures have been developed as a result of the progress made in synthetic procedures and characterization techniques. Since these liquid crystals exhibit new functions and properties derived from their nanostructures and alignment, a variety of new functions for liquid crystals, such as transport for energy applications, separation for environmental applications, chromism, sensing, electrooptical effects, actuation, and templating have been proposed. This Review presents recent advances of liquid crystals that should contribute to the next generation of materials.

“…Es wurde berichtet, dass Blaue Phasen, die doppelt‐chirale nematische Strukturen aufweisen, schnelle Reaktionen zeigen, optisch isotrop sind und bei Display‐Anwendungen keinen Reibvorgang erfordern . Materialien, die Blaue Phasen bilden, wurden auch für den Einsatz in optischen Lasern untersucht . Bei diesen Anwendungen war der enge Temperaturbereich von Blauen Phasen ein gravierendes Problem.…”

Seit der Entdeckung des flüssigkristallinen Zustandes im Jahr 1888 wurden Flüssigkristalle unter Einsatz verschiedener Technologien in unterschiedlichen Disziplinen eingehend erforscht. In letzter Zeit wurden dank der Fortschritte bei Synthese‐ und Charakterisierungsmethoden ein neuartiges Moleküldesign und neue selbstorganisierte Strukturen entwickelt. Für diese Flüssigkristalle, deren neuartige Funktionen und Eigenschaften sich von ihren Nanostrukturen und ihrer Ausrichtung ableiten, wurde eine Vielzahl möglicher Anwendungen vorgeschlagen, etwa im Energietransport, in Trennverfahren für die Umwelttechnik, als Sensoren, Aktuatoren oder Template sowie auf der Grundlage von Farbänderungen oder elektrooptischen Effekten. Dieser Aufsatz präsentiert die neuesten Fortschritte bei Flüssigkristallen, die zu einer neuen Generation von Materialien führen könnten.

“…BPs have received considerable attention as light shutters in the next generation of LC displays, fast light modulators, − and tunable photonic crystals. − However, BPs generally appear over a very narrow temperature range (in most cases, less than 1 K), which has limited their practical applicability . Several theoretical studies have been attempted, − and many experiments have been carried out to widen the temperature range of BPs.…”

Simple and Efficient Chiral Dopants to Induce Blue Phases and Their Optical Purity Effects on the Physical Properties of Blue Phases

et al. 2014

Blue phases (BPs) have received considerable attention as light shutters in the next generation of liquid crystal (LC) displays. However, no simple and efficient chiral dopant for induction of BPs of commercially available rodlike LC compounds has been reported. In this study, both (R) and (S) forms of novel chiral dopants were synthesized, showed extremely high helical twisting power values in nematic LC compounds, and induced stable BPs with a small amount of our chiral dopants (3-5 mol %). In enantiomeric excess controlled experiments, we found novel phenomena in their physical properties, such as generation of a metastable chiral nematic phase between an isotropic state and a BP.
