摘要

In order to obtain a polarization sensitive materials with improved characteristics, there was conducted intensify interaction between the components of recording media through the interaction between the molecular electrostatic forces. For creating materials there were used various organic dyes capable of photochemical geometric isomerization under the influence of actinic polarized light with a wavelength closed to the maximum of the absorption spectrum of each dye. Various polarization sensitive materials have been synthesized based on the polar water-soluble components. Substantial improvement photoanisotropic characteristics of these materials are revealed due to previously added ionizing functional groups in the chromophoric components. It is shown particular exemplary embodiment of synthesis the materials composed of dyes which communicate with certain polymers via dipole-ionic bonds. The research data of medium properties on their base have been brought up for the consideration. In the same way photoanisotropic materials are created on basis of various polar polymer matrixes which separate macromolecules are capable of establishing dipole-dipole bonds with each other. Thanks to this circumstance a supplementary number of polymer fragments which cannot afford direct connection with dye molecules are also able to get drawing into the photoanisotropy inducting processes. It is displayed the influence of such interactions on material kinetics and value of attainable photoanisotropy. A capability of achievement extremely high values of photoanisotropy is produced on the material samples based on the dyes with expanded number of ionized substituent.
