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.

Formation of a Cubic Liquid Crystalline Nanostructure with π-Conjugated Fluorinated Rods on the Gyroid Minimal Surface

Formation of a Cubic Liquid Crystalline Nanostructure with π‐Conjugated Fluorinated Rods on the Gyroid Minimal Surface

The power of fluorination: Tailoring the fluorination pattern modifies the soft self-assembly of oligo(phenylene ethynylene)-based X-shaped polyphiles, leading to the first thermotropic liquid crystalline cubic phase with the π-conjugated rods forming the gyroid minimal surface. The organization of the rods perpendicular to the minimal surface and parallel to each other allows π-stacking interactions in all three dimensions of space (see figure).

Macroscopically Oriented Porous Materials with Periodic Ordered Structures: From Zeolites and Metal–Organic Frameworks to Liquid-Crystal-Templated Mesoporous Materials

Macroscopically Oriented Porous Materials with Periodic Ordered Structures: From Zeolites and Metal–Organic Frameworks to Liquid‐Crystal‐Templated Mesoporous Materials

Porous materials, such as zeolites, metal–organic frameworks, and mesoporous silica, are usually prepared as assemblies of randomly oriented microdomains. However, if their channels are unidirectionally oriented over a large area, highly controlled spatial arrangement of guest molecules becomes possible, leading to efficient separation, sensing, transfer, and arraying of molecules. An overview of recent studies on such oriented porous materials is provided.

Self-Assembled Liquid-Crystalline Ion Conductors in Dye-Sensitized Solar Cells: Effects of Molecular Sensitizers on Their Performance

Self‐Assembled Liquid‐Crystalline Ion Conductors in Dye‐Sensitized Solar Cells: Effects of Molecular Sensitizers on Their Performance

Bright future: Nanostructured liquid crystals forming self-assembled two-dimensional ion-transport pathways have been applied as electrolytes in dye-sensitized solar cells (DSSCs; see figure). DSSCs based on these liquid-crystalline (LC) electrolytes and organic dye sensitizers show more efficient energy conversion than LC-DSSCs based on ruthenium metal–organic dyes.

Infrared Regulating Smart Window Based on Organic Materials

Infrared Regulating Smart Window Based on Organic Materials

In this review, smart windows are discussed which reflect excess of solar energy (infrared radiations) in summer and allow entrance into the building during winter, without interfering with visible light, to save significant amounts of energy in heating, cooling and lighting.
