Frustrated phases induced in binary mixtures of hockey-stick and chiral rod-like mesogens
Result description
Two liquid crystalline compounds with different shape and chirality aspect have been used to prepare binary mixtures. Achiral hockey stick mesogen exhibiting a nematic - smectic C synclinic-smectic C anticlinic phase sequence has been blended with a chiral rod-like mesogen with SmA- ferroelectric (FE) SmC* - antiferroelectric (AF) SmCA*phase sequence. Several frustrated phases (blue phases, TGBA and TGBC phases) have been induced in a broad temperature and concentration ranges. By tailoring the composition of the chiral compound we succeeded in preparation of mixtures with unusual mesomorphic behaviour. We demonstrate a new system showing chiral nematic and antiferroelectric phase in its phase sequence.
