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.

Weak Anchoring Interface Inducing Acrylate Copolymer Designs for High-Performance Polymer-Stabilized Blue Phase Liquid Crystal Displays

Weak Anchoring Interface Inducing Acrylate Copolymer Designs for High‐Performance Polymer‐Stabilized Blue Phase Liquid Crystal Displays

We demonstrated a unique way to reduce the driving voltage of polymer stabilized blue phase liquid crystal (PS-BPLC) based on stabilizing the BPLC with weak anchoring interface inducing acrylate monomers. The as-prepared PS-BPLC showed significant voltage reduction, while maintaining the other electro-optical properties of BPLCs within the desired limits. This weak anchoring approach has a great potential in developing high-performance photonic devices and displays.

On the Dimensional Control of 2 D Hybrid Nanomaterials

On the Dimensional Control of 2 D Hybrid Nanomaterials

Organic/inorganic hybrid lamellar nanomaterials have been prepared using photopolymerizable hydrogen-bonded thermotropic liquid crystals with different cross-linkers. Inside the nanopores, the size of the metal nanoparticles is controlled by tuning the cross-linker length.

Room-Temperature Columnar Nematic and Soft Crystalline Columnar Assemblies of a New Series of Perylene-Centred Disc Tetramers

Room‐Temperature Columnar Nematic and Soft Crystalline Columnar Assemblies of a New Series of Perylene‐Centred Disc Tetramers

Stacked columns: New perylene-centred disc tetraester derivatives that show soft crystal columnar behaviour and a nematic columnar mesophase at room temperature over a wide temperature range have been designed and synthesised (see figure; Crcolob=soft crystal columnar oblique, Ncol=columnar nematic). These materials may find applications in optoelectronic and solid-state devices.

Development of New Supramolecular Lyotropic Liquid Crystals and Their Application as Alignment Media for Organic Compounds

Development of New Supramolecular Lyotropic Liquid Crystals and Their Application as Alignment Media for Organic Compounds

All lined up: New lyotropic liquid-crystalline phases based on benzenetricarboxamides are used as alignment media for organic solvents. A chiral alignment medium can be obtained by blending a chiral benzenetricarboxamide into an achiral lyotropic liquid crystal at a molar ratio as low as 190:1.

Polymer-Stabilized Micropixelated Liquid Crystals with Tunable Optical Properties Fabricated by Double Templating

Polymer‐Stabilized Micropixelated Liquid Crystals with Tunable Optical Properties Fabricated by Double Templating

An anisotropic polymer network with a micropixelated structure is fabricated by photopolymerization of a self-organized pattern of a nematic liquid crystal (NLC). It is demonstrated that the network in turn imprints other nonpolymerizable NLC molecules, which maintains their responses to electric field and temperature. Various applications are introduced depending on the concentration of polymer network.
