Journal ArticleDOI
Polar Order, Mirror Symmetry Breaking, and Photoswitching of Chirality and Polarity in Functional Bent-Core Mesogens
Mohamed Alaasar,Mohamed Alaasar,Marko Prehm,Sebastian Belau,Nerea Sebastián,Marharyta Kurachkina,Alexey Eremin,Changlong Chen,Feng Liu,Carsten Tschierske +9 more
TL;DR: Fine-tuning of the molecular structure leads to photoresponsive bent-core (BC)LCs exhibiting a fast and reversible photoinduced change of the mode of the switching between ferroelectric- and antiferro electric-like as well as a light-induced switching between an achiral and a spontaneous mirror-symmetry-broken LC phase.
Journal ArticleDOI
Liquid crystalline self-assembly of 2,5-diphenyl-1,3,4-oxadiazole based bent-core molecules and the influence of carbosilane end-groups
Eduard Westphal,Eduard Westphal,Hugo Gallardo,Nerea Sebastián,Alexey Eremin,Marko Prehm,Mohamed Alaasar,Mohamed Alaasar,Carsten Tschierske +8 more
TL;DR: In this paper, a transition from non-modulated via modulated synclinic SmC phases to optically almost isotropic sponge phases was observed with growing packing density upon lowering temperature, which was investigated in the bulk state as well as in freely suspended films.
Journal ArticleDOI
Disentangling molecular motions involved in the glass transition of a twist-bend nematic liquid crystal through dielectric studies.
David López,Nerea Sebastián,M. R. de la Fuente,J. C. Martínez-García,Josep Salud,M. A. Perez-Jubindo,S. Diez-Berart,David Dunmur,Geoffrey R. Luckhurst +8 more
TL;DR: Broadband dielectric spectroscopy has been used to study the molecular orientational dynamics of the glass-forming liquid crystal 1",7"-bis (4-cyanobiphenyl-4'-yl)heptane (CB7CB) over a wide temperature range of the twist-bend nematic phase, and the critical-like description via the dynamic scaling model seems to give quite good numerical fittings.
Journal ArticleDOI
Doping of nematic cyanobiphenyl liquid crystals with mesogen-hybridized magnetic nanoparticles
Ingo Appel,Ingo Appel,Hajnalka Nádasi,Christian Reitz,Nerea Sebastián,Horst Hahn,Alexey Eremin,Ralf Stannarius,Silke Behrens,Silke Behrens +9 more
TL;DR: The coupling of the ultrasmall, spherical MNPs with the LC director in the magnetic field suggests the formation of LC-induced, anisometric MNP clusters, and homogenous MNP@ML-5CB hybrids with long-term, colloidal stability are obtained after magnetic separation of initially formed particle aggregates.
Journal ArticleDOI
Emergence of polar order and tilt in terephthalate based bent-core liquid crystals.
Nerea Sebastián,Sebastian Belau,Alexey Eremin,Mohamed Alaasar,Mohamed Alaasar,Marko Prehm,Carsten Tschierske +6 more
TL;DR: It is demonstrated the growth of ferroelectric domains in the paraelectric SmA phase, which adopt antipolar correlations (SmAPAR) and eventually condense into a weakly tilted antiferroelectric smectic phase (SmCaPA).
