Lyotropic chromonic liquid crystals (LCLCs) are known to form a columnar discotic liquid crystalline (LC) phase in aqueous solution by molecular self-assembly due to the strong π-π interaction between the aromatic cores of chromonic dye molecules,and ionic interaction of charged peripheries.[1,2] The aqueous solution of these LCLCs can be coated on a substrate such as glass or plastic with maintaining the LC phase.After the removal of solvent,the self-assembled columnar structure can form a crystalline thin film.Thus,if such columnar structures can be anisotropically oriented by a special coating technique such as a shear coating,the resulting thin crystal film can absorb a polarized light parallel to the molecular axis transmitting a polarized light parallel to the columnar axis to form E-polarizer.
