“…Also thermotropic liquid crystals can be very useful as templates in various contexts, realizing a solid either by polymerizing the liquid crystalline phase [42,43] or by polymerizing another material inside the liquid crystal [44,45]. A particularly beautiful example of the latter approach is the successful production of helical polyacetylene fibers by polymerizing acetylene gas in a chiral nematic reaction field, a strategy pioneered by Hideki Shirakawa and Kazuo Akagi and co-workers at Kyoto University, Japan [46].…”

a b s t r a c tLiquid crystals constitute a fascinating class of soft condensed matter characterized by the counterintuitive combination of fluidity and long-range order. Today they are best known for their exceptionally successful application in flat panel displays, but they actually exhibit a plethora of unique and attractive properties that offer tremendous potential for fundamental science as well as innovative applications well beyond the realm of displays. Today this full breadth of the liquid crystalline state of matter is becoming increasingly recognized and numerous new and exciting lines of research are being opened up. We review this exciting development, focusing primarily on the physics aspects of the new research thrusts, in which liquid crystals e thermotropic as well as lyotropic e often meet other types of soft matter, such as polymers and colloidal nano-or microparticle dispersions. Because the field is of large interest also for researchers without a liquid crystal background we begin with a concise introduction to the liquid crystalline state of matter and the key concepts of the research field. We then discuss a selection of promising new directions, starting with liquid crystals for organic electronics, followed by nanotemplating and nanoparticle organization using liquid crystals, liquid crystal colloids (where the liquid crystal can constitute either the continuous phase or the disperse phase, as droplets or shells) and their potential in e.g. photonics and metamaterials, liquid crystal-functionalized polymer fibers, liquid crystal elastomer actuators, ending with a brief overview of activities focusing on liquid crystals in biology, food science and pharmacology.

“…To increase the degree of the surface anisotropy we include in our photoalignment materials a photoreactive material, which is a liquid crystalline. First, we tested a photo polymerisable thermotropic liquid crystal material Paliocolor LC242 (BASF) [22]) which has a nematic phase in the interval 30°C N 125°C on cooling and 63-70°C N 125°C on heating (see Figure 3). Paliocolor LC242 (or PLC242) was designed and synthesised for production of optical compensating films.…”

To improve the characteristics and quality of the photoalignment of liquid crystals has been a main goal of many relevant studies. We demonstrate in this work, following the general concept of composite materials, that the photoalignment of liquid crystal can substantially be improved when using alignment layers made from photoalignment composite materials. These composites contain at least one photoalignment material. The other components of the photoalignment composite material may or may be not photosensitive, as conventional polyimide materials, for instance.We show that by a proper choice of the components, the properties of the photoalignment materials, made by photoalignment composites, can be tailored in a broad range, resulting in higher sensitivity, and thus shorter exposure time, uniform and smooth photoalignment topography (without domains and sandy structures) resulting in high image contrast. High-quality photopatterning of the liquid crystal alignment is demonstrated in this work with a photoalignment composite material containing one of our photoalignment materials and a conventional polyamide alignment material.
