Název v původním jazyce

Induced blue phase and twist grain boundary phase in binary mixtures of chiral calamitic and achiral hockey stick-shaped liquid crystals

Popis výsledku v původním jazyce

Frustrated phases in chiral liquid crystalline systems, such as the blue phase (BP) and the twist grain boundary (TGB) phase, can create new opportunities in liquid crystal research. A new binary mixture system composed of chiral rod-like FLC and an achiral hockey stick-shaped compound was designed. This binary system exhibits induced frustration, resulting in the emergence of the BP-III and TGBA* phases. We report a comprehensive study on several binary mixtures designed of chiral ferroelectric LC derived from the lactic acid and achiral hockey stick shaped compound. These mixtures exhibit induced the blue phase (BP-III,~2.5-6.2K) and the twist grain boundary smectic A* phase (TGBA*~1.8-6K). The results obtained by various experimental techniques are discussed in the relation to the molecular structure of the used materials.
