Liquid crystalline dimers containing a cholesteryl group: chiral smectic phases and TGBA* phase

Liquid crystalline dimers containing a cholesteryl benzoate unit: smectic phase, chiral nematic phase and blue phase

“…IR and 1 H-NMR data are given in the literature. 18 2.3.3. (E)-4-((4-(hexyloxy)phenyl)diazenyl)phenol (DN-6).…”

“…The presence of flexible spacer chains and terminal groups provides plenty of opportunities to easily modify the thermal properties and phase transition behaviour of dimeric liquid crystals. 15 The mesophases of dimeric liquid crystals are quite abundant, containing chiral nematic phases, 16 a variety of smectic phases, 17,18 frustrated twist grain boundary phases, 19,20 and mysterious and fascinating blue phases, 21,22 which has aroused great interest.…”
