M. Żurowska,Roman Dąbrowski,Jerzy Dziaduszek,Katarzyna Garbat,M. Filipowicz,Marzena Tykarska,W. Rejmer,Krzysztof Czupryński,A. Spadło,Noureddine Bennis,José Manuel Otón +10 more
TL;DR: The synthesis and properties of a few dozen highly evolved analogues of (S)-MHPOBC are reported in this paper, as evidenced by polarized optical microscopy and differential scanning calorimetry, respectively.
Journal ArticleDOI
Phase transitions from the isotropic liquid to liquid crystalline mesophases studied by linear and nonlinear static dielectric permittivity
TL;DR: Despite significant differences between N, Sm-A, and Sm-E phases the same pretransitional behavior of epsilon and NDE in the isotropic phase, described by critical exponents gamma = 1 and alpha = 0.5, was found.
Journal ArticleDOI
Synthesis and Mesomorphic Properties of Chiral Esters Comprising Partially Fluorinated Alkoxyalkoxy Terminal Chains and a 1-methylheptyl Chiral Moiety
M. Żurowska,Roman Dąbrowski,Jerzy Dziaduszek,Krzysztof Czupryński,Katarzyna Skrzypek,M. Filipowicz +5 more
TL;DR: In this paper, two structurally similar homologous series of chiral esters with partially fluorinated alkoxyalkoxy terminal chains are described and their synthetic routes and mesomorphic properties, such as phase transitions temperatures and enthalpies, are characterized by polarizing optical microscope and differential scanning calorimetry.
Journal ArticleDOI
An assessment of carborane-containing liquid crystals for potential device application
TL;DR: Two 4-alkoxyphenyl 12-pentylcarborane-1-carboxylate nematic liquid crystals have been synthesized in this article, which exhibit ideal mixing of nematic phases in their binary mixtures with analogous bicyclo[2.2] octane derivatives and with the polar nematogen 4-(4-isothiocyanatophenyl)-1-(trans-hexyl)cyclohexane.
Journal ArticleDOI
X-ray diffraction, optical birefringence, dielectric and phase transition properties of the long homologous series of nematogens 4-(trans -4′- n -alkylcyclohexyl) isothiocyanatobenzenes
TL;DR: In this article, the effect of chain length on various physical properties of the CHBT series is discussed and the temperature dependence of density, refractive indices, apparent molecular length and intermolecular distance of 11CHBT, together with the static dielectric permittivities, e∥, e┴, e iso of 11 CHBT and 12 CHBT, are reported.
