ABSTRACT:
Sulfoderivatives of perylenetetracarboxylic acid dibenzimidazole are provided. These compounds form liquid crystal systems possessing high quality optical properties. The resulting liquid crystal systems are readily applicable onto a substrate to obtain optically isotropic or anisotropic, at least partially crystalline films applicable in various fields.
