PCT No. PCT/US94/05493 Sec. 371 Date Nov. 20, 1995 Sec. 102(e) Date Nov. 20, 1995 PCT Filed May 20, 1994 PCT Pub. No. WO94/28073 PCT Pub. Date Dec. 8, 1994Polarizing coatings are formed from dyestuffs which provide a stable liquid crystalline phase in a wide range of concentrations, temperatures and pH-values. Particles formed by aggregates of the liquid crystal molecules are oriented in a predetermined direction to polarize light. The stability of the liquid crystalline state allows orienting the particles by mechanical forces such as a shearing force applied when the liquid crystal (10) is spread on a support surface (20) by a knife-like doctor (90) or a tension deformation force acting on the meniscus of the liquid crystal deposited between two surfaces (20, 30) as the surfaces are peeled off one another. As a result, the polarizing coatings are formed in some embodiments by simple methods. In some embodiments, the polarizing coatings have a high lightfastness, a high thermal stability, and a high dichroic ratio.

30 Sulfoderivatives of indanthrone, lyotropic liquid crystal system and anisotropic film on their base US11046338 2005-01-27 US06962734B2 2005-11-08 Victor V. Nazarov; Elena N. Sidorenko
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.
