Abstract

The present invention is related to the synthesis of acenaphthoquinoxaline sulfonamide derivatives and the manufacture of optical crystal films based on these compounds. Said acenaphthoquinoxaline sulfonamide heterocyclic derivatives have the general structural formula: where n is 1 , 2 or 3; X is an acid group; m is 1, 2 or 3; Y is a counterion selected from the list consisting of H+, NH4+, Na+, K+, and Li+; p is the number of counterions providing neutral state of the molecule; R is a substituent selected from the list consisting of -CH3, -C2H5, -NO2, -Cl, -Br, -F, -CF3, -CN, -OH -OCH3, -OC2H5, -OCOCH3, -OCN, -SCN, -NH2, -NHCOCH3, -CONH2; and z is 1 , 2, 3 or 4.
