Anisotropic films based on sulfoderivatives of perylenetetracarboxylic acid dibenzimidazole (PTCA DBI) which contain oxo groups pendant to a perylene core. The oxo-groups, in combination with portions of the perylene core, form a quinoid system of bonds. The oxo substituted PTCA DBI sulfoderivatives form liquid crystal systems possessing high optical properties. Said liquid crystal systems can be applied onto various substrates to obtain optically isotropic or anisotropic, at least partially crystalline, films applicable in various fields.
