Interplay of polar order and positional order in liquid crystals -- observation of re-entrant ferroelectric nematic phase
Grant Strachan, Shona Ramsay, Marijus Juodka +6
We show that development of polar order may spontaneously destroy the lamellar structure of a liquid crystal. This results in an unusual sequence of phases with the ferroelectric n…
Twist Grain Boundary phases in proper ferroelectric liquid crystals realm
Damian Pociecha, Jadwiga Szydlowska, Nataša Vaupotič +7
The twist-grain-boundary (TGB) phases, characterized by a periodic, helical arrangement of blocks made of polar smectic phases, SmAF and SmCF, have been discovered. They have been…
To be or not to be polar: the ferroelectric and antiferroelectric nematic phases
Ewan Cruickshank, Paulina Rybak, Magdalena Majewska +8
We report the properties of two new series of compounds that show the ferroelectric nematic phase in which the length of a terminal chain is varied. The longer the terminal chain,…
Ferroelectric nematic -- isotropic critical end point
Jadwiga Szydlowska, Pawel Majewski, Mojca Čepič +8
A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric ne…
Intrinsically chiral ferronematic liquid crystals
D. Pociecha, R. Walker, E. Cruickshank +8
Strongly dipolar mesogenic compounds with a chiral center located in a lateral alkyl chain were synthesized, and shown to form the ferroelectric nematic phase. The presence of mole…
Multiple polar and non-polar nematic phases
S. Brown, E. Cruickshank, J. M. D. Storey +5
Liquid crystal materials exhibiting up to three nematic phases are reported. Dielectric response measurements show that while the lower temperature nematic phase has ferroelectric…
Temperature dependence of bend elastic constant in oblique helicoidal cholesterics
Olena S. Iadlovska, Greta Babakhanova, Georg H. Mehl +7
Elastic moduli of liquid crystals, known as Frank constants, are of quintessential importance for understanding fundamental properties of these materials and for the design of thei…
Nature of nematic to twist bend nematic phase transition
Damian Pociecha, Catriona Crawford, Daniel A. Paterson +4
The critical behavior at the transition from uniform nematic to twist-bend modulated nematic phase is revealed and shown to be well explained by the mean field approximation. The s…
Distinct differences in the nanoscale behaviors of the twist-bend liquid crystal phase of a flexible linear trimer and homologous dimer
Michael R. Tuchband, Daniel A. Paterson, Mirosław Salamończyk +12
We synthesized the liquid crystal dimer and trimer members of a series of flexible linear oligomers and characterized their microscopic and nanoscopic properties using resonant sof…
Electrically tunable selective reflection of light from ultraviolet to visible and infrared by heliconical cholesterics
Jie Xiang, Yannian Li, Quan Li +4
Cholesteric liquid crystals with helicoidal molecular architecture are known for their ability to selectively reflect light with the wavelength that is determined by the periodicit…
