Journal ArticleDOI
Electro-optical properties of a new series of fluorinated antiferroelectric orthoconic liquid crystalline esters
TL;DR: In this paper, the spontaneous polarisation (Ps) values of a compound with a bulky chiral unit, zigzag ester linkage and polar fluorinated terminal were investigated.
Journal ArticleDOI

TL;DR: In this paper, hockey stick-shaped mesogens with a lateral methyl group inserted between the m-alkyloxy-chain and the azomethine connecting group, 4-(3nalkylox-2-methyl-phenyliminomethyl) phenyl-4-nalklyoxycinnamates have been synthesized.
Journal ArticleDOI
Optical, dielectric and visco-elastic properties of a few hockey stick-shaped liquid crystals with a lateral methyl group
TL;DR: In this paper, the rotational viscosity coefficient of a few hockey stick-shaped compounds 4-(3n-alkyloxy-2-methyl-phenyliminomethyl)phenyl 4-nalkyloxyloxycinnamates with a lateral methyl group inserted between the malkylope chain and the azomethine connecting group was measured.
Journal ArticleDOI
Effect of molecular structure on dielectric and electro-optic properties of chiral liquid crystals based on lactic acid derivatives
TL;DR: In this paper, the properties of a few lactic acid derivatives with several ester linkage groups in the molecular core have been studied in the light of the temperature dependences of the static permittivity, dielectric anisotropy, spontaneous polarization, response time and torsional bulk viscosity for eight chiral ferroelectric liquid crystalline compounds.
Journal ArticleDOI
Rotational viscosity measurements of bent-core nematogens
TL;DR: In this paper, two simple but precise probing methods have been utilized to investigate the influence of structure, properties and molecular association on the director response time (τ0) and hence on the rotational viscosity (γ1) in the nematic phase of three 4-cyanoresorcinol bent-core derivatives (1/7, 1/9 and 1/10) having different terminal chain lengths.
