Dipole-dipole correlations in the nematic phases of symmetric cyanobiphenyl dimers and their binary mixtures with 5CB
Evangelia E. Zavvou, Efthymia Ramou, Ziauddin Ahmed +4
We report on the temperature dependence of birefringence and of the static dielectric permittivity tensor in a series of binary mixtures between the symmetric, bent-shaped, 1",9"-b…
The interplay between spatial and heliconical bond order in twist-bend nematic materials
Rony Saha, Chenrun Feng, Chris Welch +6
The nanostructure of two novel sulfur containing dimer materials has been investigated experimentally by hard and by resonant tender X-ray scattering techniques. On cooling the dim…
Molecular biaxiality determines the helical structure -- Infrared measurements of the molecular order in the NTB phase of difluoro terphenyl dimers
Katarzyna Merkel, Barbara Loska, Chris Welch +2
IR polarized spectroscopy was employed, to obtain the three components of IR absorbance for a series DTC5Cn (n=5,7,9,11) of bent-shaped dimers containing double fluorinated terphen…
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…
Tuning selective reflection of light by surface anchoring in cholesteric cells with oblique helicoidal structures
Olena S. Iadlovska, Graham R. Maxwell, Greta Babakhanova +4
Selective reflection of light by oblique helicoidal cholesteric (ChOH) can be tuned in a very broad spectral range by an applied electric field. In this work, we demonstrate that t…
