Liquid Crystals

Liquid crytals (LCs) are probably the most exciting state of matter. They attract scientists across disciplines such as chemistry, physics, materials science, and engineering—theorists and experimentalists alike. These days, you can buy quite affordable LCD TV sets around the corner, but that's just one of the many things liquid crystals can do. The selection of recent research articles presented below illustrates the broad interest in this area of soft condensed matter.

A Lyotropic Liquid-Crystal-Based Assembly Avenue toward Highly Oriented Vanadium Pentoxide/Graphene Films for Flexible Energy Storage

A Lyotropic Liquid‐Crystal‐Based Assembly Avenue toward Highly Oriented Vanadium Pentoxide/Graphene Films for Flexible Energy Storage

A novel lyotropic liquid-crystal-based assembly strategy is developed for the first time to fabricate composite films of vanadium pentoxide nanobelts and graphene oxide sheets with highly oriented layered structures. The resulting films manifest high electrical conductivity, good mechanical stability, and excellent flexibility, which allow them to be utilized as high performance electrodes in flexible energy storage devices.

Kibble–Zurek Scaling during Defect Formation in a Nematic Liquid Crystal

Kibble–Zurek Scaling during Defect Formation in a Nematic Liquid Crystal

Finding fault: The Kibble–Zurek scaling for defect formation is confirmed for a nematic liquid crystal system, where the transition from a uniform state to a defect state was achieved by electric field application. A scaling exponent of α=1/2 was obtained for different materials and independent of temperature.

A Multiple Controllable Sol–Gel Preparation of 2D Silica Lamellar Composites Based on Azoimidazolium Surfactants

A Multiple Controllable Sol–Gel Preparation of 2D Silica Lamellar Composites Based on Azoimidazolium Surfactants

A controllable sol–gel strategy toward 2D silica composites: Based on the unique structure and properties of azoimidazolium combining from the imidazolium and the azobenzene unit, a light, thermal, substrate, and mechanical control of the orderliness and its anisotropy of 2D silica lamellar composites are achieved. A method to fabricate Au nanoparticles wrapped inside 2D silica layer is also derived.

An Optically Isotropic Antiferroelectric Liquid Crystal (OI-AFLC) Display Mode Operating over a Wide Temperature Range using Ternary Bent-Core Liquid Crystal Mixtures

An Optically Isotropic Antiferroelectric Liquid Crystal (OI‐AFLC) Display Mode Operating over a Wide Temperature Range using Ternary Bent‐Core Liquid Crystal Mixtures

Perfectly black in any viewing angle: An optically isotropic antiferroelectric liquid crystal display mode is realized by using ternary bent-core liquid crystal mixtures, forming a polar antiferroelectric tilted smectic phase. The newly developed mixtures show an ideal tilt of 45°, permitting perfect black in the transformed, electric-field OFF state, and switch under an applied electric field from below room temperature to 100 °C.

From 1,4-Phenylenebis(phenylmaleate) to a Room-Temperature Liquid-Crystalline Benzo[ghi]perylene Diimide

From 1,4‐Phenylenebis(phenylmaleate) to a Room‐Temperature Liquid‐Crystalline Benzo[ghi]perylene Diimide

Flattening: Despite the presence of four ester substituents, the intramolecular Scholl reaction of tetraethyl [5]helicene-5,6,9,10-tetracarboxylate leads in fair yield to a moderately electron-deficient benzoperylene diimide with a remarkably stable mesophase.

A Family of Amphiphilic Cyclodextrin Liquid Crystals Governed by Dipole–Dipole Interactions

A Family of Amphiphilic Cyclodextrin Liquid Crystals Governed by Dipole–Dipole Interactions

Beyond hydrogen bonding: Amphiphilic cyclodextrin (CD)-based liquid crystals have been synthesized that bear O-acetylated oligoethylene glycol chains at the secondary face and thioalkyl groups at the primary face. These compounds self-assemble via dipole–dipole interactions to form highly ordered smectic liquid crystal phases with useful properties.
