Abstract: Two-phase film materials and methods for their fabrication are provided. The two-phase film materials typically comprise a first phase, comprising a crystalline film of supramolecules and a second phase, comprising a polymer film. The method of fabricating two-phase film materials comprise the steps of preparing a lyotropic liquid crystal of supramolecules comprising molecules of organic compound comprising at least one polar group; depositing a layer of the lyotropic liquid crystal; applying an external orienting action to the LLC layer; and treating the LCC layer with a binding agent.

Abstract: Optically anisotropic films based on sulfoderivatives of 1,8- naphthoylene-1?,2?-benzimidazole are disclosed. These compounds form stable lyotropic liquid crystal systems that exhibit excellent optical properties with films that are significantly thinner that the current state of the art. The lyotropic liquid crystal systems may be deposited on substrates for use in a wide variety of commercial applications.

Abstract: The present invention relates to organic chemistry, in particular, to synthesis of sulfoderivatives of the polycyclic compounds and fabrication of optically anisotropic coatings on their base. The indanthrone sulfoderivatives of the general structural formulas I or II capable of forming LLC phase are disclosed. The disclosed compounds could be used, in particular, for producing optically isotropic or anisotropic and at least partially crystalline films. The application also includes the liquid crystal systems based on the disclosed compounds, and anisotropic films. wherein n is 3 or 4, R?CH3, C2H5, OCH3, OC2H5, Cl, Br, OH, NH2, z is the value selected from the list including 0, 1, 2, 3, and 4, M—counterion, and j—number of counterions in a dye molecule, and which can be fractional in case of one counterion belonging to several molecules, and in case n>1, counterions may be different.

Abstract: Anisotropic films based on sulfoderivatives of perylenetetracarboxylic acid dibenzimidazole (PTCA DBI) which contain oxo groups pendant to a perylene core. The oxo-groups, in combination with portions of the perylene core, form a quinoid system of bonds. The oxo substituted PTCA DBI sulfoderivatives form liquid crystal systems possessing high optical properties. Said liquid crystal systems can be applied onto various substrates to obtain optically isotropic or anisotropic, at least partially crystalline, films applicable in various fields.
