Anopore confinement in the cyanobiphenyl-based liquid crystal dimer CB7CB. A dielectric study
(2024-08-01)
Article
Open AccessWe report an experimental work on the liquid crystal dimer 1’’,7’-bis(4-cyanobiphenyl-4’-yl) heptane (CB7CB) confined to Anopore membranes. We have studied the behaviour of the dielectric relaxation modes in the isotropic ... -
Comparative dielectric and thermally stimulated-depolarization-current studies of the liquid crystal dimers 1¿,9¿-bis(4-cyanobiphenyl-4'-yl) nonane and heptane and a binary mixture between them, close to the glass transition
(American Institute of Physics (AIP), 2022-11-21)
Article
Open AccessWe have performed dielectric spectroscopy and thermally stimulated-depolarization-current experiments to study the molecular dynamics of the twist-bend nematic phase close to the glass transition of two members of the ... -
DNMR measurements of an asymmetric odd liquid crystal dimer: determination of the intramolecular angle and the degree of order of the two rigid cores
(Royal Society of Chemistry (RSC), 2023)
Article
Open AccessIn this work, we present a Deuteron Nuclear Magnetic Resonance (DNMR) study of the non-symmetric odd liquid crystal dimer a-(4-cyanobiphenyl-4'-yloxy)-¿-(1-pyrenimine-benzylidene-4'-oxy) heptane (CBO7O.Py), formed by a ... -
Influence of internal flexibility on the double glass transition in a series of odd non-symmetric liquid crystal dimers characterised by dielectric measurements
(2017-04-11)
Article
Open AccessDielectric measurements (thermally stimulated depolarisation currents and broadband dielectric spectroscopy) have been performed near the glass transition to study the glass transition on the odd non-symmetric liquid crystal ... -
Molecular dynamics of a binary mixture of twist-bend nematic liquid crystal dimers studied by dielectric spectroscopy
(American Chemical Society (ACS), 2016-06-21)
Article
Open AccessWe report a comprehensive dielectric characterization of a liquid crystalline binary mixture composed of the symmetric mesogenic dimer CB7CB and the nonsymmetric mesogenic dimer FFO9OCB. In addition to the high-temperature ... -
Steepness-fragility insights from the temperature derivative analysis of dielectric data of a highly nonsymmetric liquid crystal dimer
(American Institute of Physics (AIP), 2024-08-12)
Article
Open AccessA comprehensive dynamic analysis of the dielectric relaxation-time data across a broad temperature range for both isotropic and nematic phases has been conducted on the CBO3O.Py liquid crystal dimer, the shorter chain-length ...
