Abstract
A diacetylene-based lyotropic liquid crystal mixture according to an embodiment includes by mixing diacetylene-based compounds containing iodide and triiodide Chemical Formula 1 and Chemical Formula 2. The lyotropic liquid crystal mixture may be prepared by synthesizing an [X]—C—Rm-[D]-Rn compound, synthesizing an [A+X−]—C—Rm-D-Rn compound, and synthesizing an [A+B−]—C—Rm-D-Rn compound. A thin polarizing film may be prepared through simple coating of a lyotropic liquid crystal mixture prepared by mixing diacetylene-based compounds containing iodide and triiodide.
