Structural,Optical and Mechanical Features of the Nanostructured Organic Materials: Possible Applications in Optoelectronics

摘要

Structural, optical and mechanical properties of nanostructured organic materials were studied under the nanostructurization condition. The principal aim of this study is to show how the different types of the nanoob- jects modify the structural and photorefractive properties of nanostructured materials. The properties of the organic nanoobjects-doped composites are studied in view of their application in optoelectronics. A common polymer, polyimide and liquid crystal matrices from cyanobiphenyl group are chosen as a good model to increase the local volume polariz- ability via the formation of an intermolecular charge transfer complex. 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, that can be responsible for the high speed display elements, laser switchers, medicine instruments improvements, etc. Moreover, some mechanical achievements of the nanoobjects-containing network are observed.
