Abstract :

The unique special electrical, magnetic, thermooptical, and nonlinear optical features of the liquid crystals (LCs) mesophase permit to apply them in optical information processing schemes, laser physics, display technique, and medicine. LC modulates the laser beam, converts the frequency, attenuates the light signals and orients particles suspended in them. Thus, LC systems act as molecular matrices, which are easily controlled by an external field. Moreover, because of the interaction between the matrix and the particles suspended in it, the latter become sensitive to the external field, with the result that the orientation of the LC matrix also changes. Recent ten years show the new approaches based on the nanostructurizationprocess which permit to study and apply the LC materials with good advantage. In the present paper the structural, spectral, optical, and photorefractive features of the liquid crystal organic materials are studied under the nano- and biostructurization conditions. The main accent is given to show the perspective of the different types of the nano- and boiobjects to modify the structural and photorefractive properties. Basic matrix, namely, liquid crystal one from cyanobiphenyl groups is chosen as the good model to increase the local volume polarizability via intermolecular charge transfer complex formation. Special role of the dipole moment as a macroscopic parameter of a medium accounts for a relationship between the photorefraction and the photoconductivity characteristics and it can be considered as an indicator of following dynamic parameters change. Moreover, some mechanical achievement of the nanoobjects-containing network is observed and the aligning of the DNA molecules is shown to support the old our idea to align theerythrocytes cells in the LCs. Possible applications of these organic nano- and bioobjects-doped liquid crystal composites are discussed to apply them in the material sciences, photophysics, chemistry, and biology.
