Paper Abstract

The paper presents the results of a study of the spatial structure of Si-containing [poly(ethynediyl-arylene-ethynediyl-silylene)] composites in the nanometer scale, as well as of an optical study of photorefractive effects in the visible and near-infrared ranges in these composites. The compositions have been examined using transmission/diffraction electron microscopy. The results suggest the existence of an extraordinary self-organisation in conjugated silicon organometallic polymers (nano-structured layers with a spatial period of several nanometers and the length of more than 100 nm). The most probable mechanism of the structure formation is π-stacking of the aromatic groups with the poly(phenylsilsesquioxane) matrix as a template. The observed self-organisation is very important for the understanding of the infrared photorefractive effect in the organometallic polymer compositions. Two-wave mixings in the Raman-Nath and Bragg modes were used to study non-linear optical properties in the visible (632 nm) and near-infrared (1500 nm) spectral ranges. Both local and non-local types of refractive index gratings have been observed.
