Using the experimental data on the dielectric anisotropy, density, polarizability, dipole moment, and order parameter in the nematic phase of seven typical liquid crystalline substances, the applicability of the Maier-Meier theory for the description of the dielectric properties of nematics is checked. Substances with different polarity and different tendency to form associates in the nematic phase were studied. It is found that the Maier-Meier equations describe fairly well the dielectric permittivity components of nematics. The estimated values of the angle ß formed by the dipole moment with the long molecular axis are compared with those obtained in other studies.

“…6CHBT has a dipole moment created mainly by the-NCS group which is a little smaller than that of the -CN group ( Table 2). The substance exhibits a moderate tendency to form antiparallel dimers in the nematic phase [16][17][18]. The fit shown in Fig.…”

“…The ratio d/h is equal to 6.8 and corresponds to the birefringence 0.15. This value agrees with the tabulated value of ∆n for LC 6CHBT [17][18][19] and confirms that the LC is in the highly ordered state. …”

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.

The paper reviews and discusses the latest developments in the field of the photonic liquid crystal fibers that have occurred for the last three years in view of new challenges for both fiber optics and liquid crystal photonics. In particular, we present the latest experimental results on electrically induced birefringence in photonic liquid crystal fibers and discuss possibilities and directions of future developments.
