ABSTRACT:
Optically anisotropic films based on sulfoderivatives of 1,8-naphthoylene-1′,2′-benzimidazole are disclosed. These compounds form stable lyotropic liquid crystal systems that exhibit excellent optical properties with films that are significantly thinner that the current state of the art. The lyotropic liquid crystal systems may be deposited on substrates for use in a wide variety of commercial applications.
