Abstract
Anisotropic films based on sulforderivatives of phenanthro-9′,10′:2,3-quinoxaline are disclosed. These compounds form liquid crystal and lyotropic liquid crystal systems that exhibit excellent optical properties with films that are significantly thinner than the current state of the art. The liquid crystal systems may be deposited on substrates or other film materials for use in a wide variety of commercial applications.
