Synthesis of highly chiral multisubstituted binaphthyl compounds as potential new biaxial nematic and NLO materials

Helical Polyacetylene: Asymmetric Polymerization in a Chiral Liquid-Crystal Field

“…These properties are attributed to large steric repulsions between hydrogens at the 8-and 8′-positions in the naphthyl rings. 107,111,148 It is also confirmed from this figure that the helical twisting power of the binaphthyl derivative slightly decreases with increasing temperature.…”

An unusual phase sequence of iso liq-blue phase-smectic A observed for novel binaphthyl mesogenic derivatives

“…In the present study, we have prepared a homologous series of dimeric liquid-crystalline compounds possessing a binaphthyl group ((R)-n) and found an unusual phase sequence of iso-BP-SmA. A few examples of binaphthyl derivatives have been reported 20,21 and some of them show chiral smectic phases, 21 however, a N* phase has not been observed for binaphthyl mesogenic derivatives.…”

Unconventional liquid crystal oligomers with a hierarchical structure

“…Some reports have described structure-property relations of binaphthyl derivatives. [89][90][91] However, the origin of the twisting power in a liquid-crystalline phase remains unclear. We designed a host-guest system to gain a better understanding of the chirality transfer from a binaphthyl derivative to a host nematic liquid crystal (Fig.…”
