Anopore confinement in the cyanobiphenyl-based liquid crystal dimer CB7CB. A dielectric study
Robles Hernández, Beatriz; Sebastián, Nerea; de la Fuente Lavin, Maria Rosario; López Pérez, David Orencio; Salud Puig, Josep; Díez Berart, Sergio (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
Sellarès González, Jordi; Diego Vives, José Antonio; López Pérez, David Orencio; Salud Puig, Josep; Robles Hernández, Beatriz; de la Fuente Lavin, Maria Rosario; Cañadas Lorenzo, Juan Carlos; Mudarra López, Miguel; López de Rioja, Víctor; Levit Valenzuela, Rafael; Díez Berart, Sergio (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
Sebastian Ugarteche, Nerea; Zupancic, Blaz; López Pérez, David Orencio; Salud Puig, Josep; López de Rioja, Víctor; Levit Valenzuela, Rafael; de la Fuente Lavin, Maria Rosario; Ros Latienda, Maria Blanca; Díez Berart, Sergio; Robles Hernández, Beatriz (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

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
Robles Hernández, Beatriz; Sebastian Ugarteche, Nerea; Salud Puig, Josep; Díez Berart, Sergio; Dunmur, D.A.; Luckhurst, G.R.; López Pérez, David Orencio; de la Fuente Lavin, Maria Rosario (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
