Journal ArticleDOI
Electrically Tunable Selective Reflection of Light from Ultraviolet to Visible and Infrared by Heliconical Cholesterics
Jie Xiang,Yannian Li,Quan Li,Daniel A. Paterson,John Storey,Corrie T. Imrie,Oleg D. Lavrentovich +6 more
TL;DR: Electrical tuning of selective reflection of light is achieved in a very broad spectral range from ultraviolet to visible and infrared by an oblique helicoidal state of a cholesteric liquid crystal in a wide temperature range (including room temperature).
Journal ArticleDOI
Understanding the twist-bend nematic phase: the characterisation of 1-(4-cyanobiphenyl-4′-yloxy)-6-(4-cyanobiphenyl-4′-yl)hexane (CB6OCB) and comparison with CB7CB
Daniel A. Paterson,Min Gao,Young-Ki Kim,Afsoon Jamali,Kirsten L. Finley,Beatriz Robles-Hernández,S. Diez-Berart,Josep Salud,M. Rosario de la Fuente,Bakir A. Timimi,Herbert Zimmermann,Cristina Greco,Alberta Ferrarini,John Storey,David López,Oleg D. Lavrentovich,Geoffrey R. Luckhurst,Corrie T. Imrie +17 more
TL;DR: A complementary extended molecular field theory was found to be in suggestive accord with the (2)H-NMR studies of CB6OCB-d2, and those already known for CB7CB-d4, including the reduced transition temperature, TNTBN/TNI, and the order parameter of the mesogenic arms in the N phase close to the NTB-N transition.
Journal ArticleDOI
Reversible Isothermal Twist–Bend Nematic–Nematic Phase Transition Driven by the Photoisomerization of an Azobenzene-Based Nonsymmetric Liquid Crystal Dimer
Daniel A. Paterson,Daniel A. Paterson,Jie Xiang,Gautam Singh,Rebecca Walker,Dena Mae Agra-Kooijman,Alfonso Martinez-Felipe,Min Gao,John Storey,Satyendra Kumar,Oleg D. Lavrentovich,Corrie T. Imrie +11 more
TL;DR: The dramatic changes in TNTBN provide evidence that the transition between the normal nematic and twist-bend nematic with spontaneous breaking of chiral symmetry is crucially dependent on the shape of molecular dimers, which changes greatly during the trans-cis isomerization.
Journal ArticleDOI
Cyanobiphenyl-based liquid crystal dimers and the twist-bend nematic phase
TL;DR: In this paper, the synthesis and characterisation of several members of the 1,ω-bis(4-cyanobiphenyl-4′-yl) alkane (CBnCB) homologous series are reported.
Journal ArticleDOI
Electrically tunable laser based on oblique heliconical cholesteric liquid crystal
Jie Xiang,Andrii Varanytsia,Fred Minkowski,Daniel A. Paterson,John Storey,Corrie T. Imrie,Oleg D. Lavrentovich,Peter Palffy-Muhoray +7 more
TL;DR: A cholesteric structure used as the laser’s resonator cavity that enables a continuous real-time tuning of the emitted wavelength in a very broad range by applying an electric field, and ensures efficiency of lasing in the entire tunable range of emission.
