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
##STR1##
- wherein n is 3 or 4,
- RCH3, 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 n1,
counterions may be different.
