“…In past years, this technique has been extensively used to align LC materials. [109][110][111][112] Recently, Chou et al demonstrated that this approach can also be applied to aligning small conjugated molecules, thereby fabricating OFETs with anisotropic electronic properties. [49] As shown in Figure 13a, on a photoaligned polyimide layer, the pentacene film is aligned perpendicularly to the polarization direction of the incident UV light, resulting in grains continuous along this direction.…”

The search for low‐cost, large‐area, flexible devices has led to a remarkable increase in the research and development of organic semiconductors, which serve as one of the most important components for organic field‐effect transistors (OFETs). In the current review, we highlight deposition techniques that offer precise control over the location or in‐plane orientation of organic semiconductors. We focus on various vapor‐ and solution‐processing techniques for patterning organic single crystals in desired locations. Furthermore, the alignment of organic semiconductors via different methods relying on mechanical forces, alignment layers, epitaxial growth, and external magnetic and electric fields are surveyed. The advantages, limitations, and applications of these techniques in OFETs are also discussed.

“…Historically, the photo-induced anisotropy recorded in the polyvinylcinnamate was first demonstrated in 1977 [1]. This material was then applied to align the liquid crystal molecules, and very promising results had been obtained [2][3]. However, the homogenous alignment cannot be restored after a number of thermal cycles.…”

“…Taking into account these features as well as the alignment direction of PVCN layers perpendicular to the light polarization [10][11][12][13][14][15][16] one can deduce that the transversal configuration presented in Fig. 1b is realized.…”

“…To model these cavities we used cylindrical capillaries of 8-25 µm in diameter. The capillary walls were covered by thin layers of polyvinylcinnamate (PVCN), photoaligning polymer providing planar anchoring with the alignment direction perpendicular to polarization axis of actinic light [10][11][12][13][14][15][16]. For this purpose, PVCN was dissolved in chlorobenzene.…”

Axial and transversal orientational configurations of a nematic liquid crystal 6CHBT are realized inside glassy cylindrical capillaries by using photoalignment technique. It is demonstrated that this principle can be effectively used to enforce liquid crystal alignment in the desirable direction. It can be applied to control liquid crystal alignment in the photonic crystal fibers showing great potential for the modern telecommunication technologies.
