Abstract Structural, spectral, optical and photorefractive features of the nanostructured organic materials are studied under the nano- and biostructurization condition. 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 polymer, namely, polyimide and liquid crystal matrixes from cyanobiphenyl groups are 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 photorefrac-tion and the photoconductivity characteristics and it can be considered as an indicator of following dynamic pa-rameters change. Moreover, some mechanical achievement of the nanoobjects-containing network is observed. Possible applications of the organic nano- and bioobjects-doped composites are discussed to apply them in the optoelectronics and biomedicine.
