Sulfoderivatives indanthrone, lyotropic liquid crystal system and anisotropic film based on them

摘要

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-CHSUB3/SUB, CSUB2/SUBHSUB5/SUB, OCHSUB3/SUB, OCSUB2/SUBHSUB5/SUB, Cl, Br, OH, NHSUB2/SUB, 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 n1, counterions may be different.
