Variability of the Smectic a Layer Spacing and Dielectric Properties in the Homologous Series of 4-Isothiocyanatophenyl 4- (Trans-4-Alkylcyclohexyl) Benzoates
Roman Dabrowski,Krzysztof Czupryński,Jan Przedmojski,J. Baran,Jan Jadżyn,Grzegorz Czechowski +5 more
TL;DR: In this paper, a homologous series of 4-isothiocyanatophenyl 4-(trans-4-alkylcyclohexyl)benzoates was synthesized and their phase transition temperatures and enthalpies, smectic layer spacing and dielectric permittivity were measured.
Journal ArticleDOI
The Elastic Constants of Nematic n-Hexylcyanobiphenyl Determined with the Capacitance Method
TL;DR: In this paper, the splay (K 11) and bend (K 33) elastic constants of n-hexylcyanobiphenyl were determined from the voltage (U) dependence of the capacitance (C) of the planar nematic cell with a small molecular pretilt angle.
Journal ArticleDOI
Non-linear dielectric effect in superpressed chiral isopentylcyanobiphenyl (5∗CB)
Sylwester J. Rzoska,Aleksandra Drozd-Rzoska,M. Górny,Jan Jadżyn,Jerzy Zioło,Krzysztof Czupryński,Roman Dąbrowski +6 more
TL;DR: In this paper, the Vogel-Fulcher-Tammann evolution of relaxation times and the broadening of loss curves on cooling were studied in a pressurized isopentylcyanobiphenyl.
Journal ArticleDOI
Non-linear dielectric studies of the isotropic-smectic phase transition in 6-DBT and 7-DBT
TL;DR: In this article, measurements of Δ∊/E 2 for 6-DBT and 7DBT were made in the isotropic phase, in the vicinity of T SA1, and for 6DBT solutions in dioxane over a broad range of temperatures.
Journal Article
