Abstract:Two new families of chiral monomers were synthesized which consisted of a spaced biphenyl core and a 2,3-disubstituted or 2,2-disubstituted oxirane ring. The former monomers formed liquid crystal mesophases, whereas the latter monomers did not generate any mesophases independent of the spacer lengths investigated. The mesogenic propensity was enhanced in chiral liquid crystals based on the biphenyl benzoate core and either oxirane ring. A linear electro-optic response was detected in the chiral nematic phase a… Show more
“…48 The synthesis and phase transition behaviour of several series of chiral epoxy liquid crystals have been studied. [49][50][51][52][53][54][55][56][57][58] However, no chiral epoxy liquid crystals have been used for the preparation of epoxy resin-based CLCN films. Herein, two pairs of epoxy liquid crystals with a cholesteric phase were synthesized, and the CLCN films with a structural colour were prepared using their mixtures.…”
Cholesteric liquid crystal polymer network (CLCN) films attracted much attention for their applications as optical filters, and for display, decoration and anti-counterfeiting. Herein, two pairs of chiral bola-type epoxy liquid...

“…Structure-mesogenity relationship plays a major role in understanding the properties of liquid crystals. Slight changes in the structural segments can make drastic effects on mesomorphic properties 8,9,10 . The occurence of tilted smectic phases of chiral calamitic liquid crystals are especially important due to their applications in display devices showing fast switching behavior 11 .…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
