TECHNOLOGY FOCUS - POLYMERS - Preparation (claimed): 1,7-Dibromo-3,4,9,10-perylene tetracid anhydride and 3,4,5-trialkoxy-1-aminobenzene are reacted in the quinoline, imidazole, butanol, N-methyl-2-pyrrolidone or propionic acid solution at 60-100 degrees C for 1-72 hours in the molar ratio of 1:3-10, to obtain perylene tetracarboxylic imidodicarbonic diamide dibromo product. The obtained 2,1,3-diazosulfide dibromo product and 2-tributyltin-3,6-dialkyl thieno(3,2-b)thiofuran are subjected to Stille coupling reaction in presence of catalyst and solvent at 50-120 degrees C for 24-72 hours in the molar ratio of 1:2-2.5, to obtain reaction product of 4,7-bis(3,6-dialkyl thieno(3,2-b)thiofuran)-2,1,3-diazosulfide. The obtained product of 4,7-bis(3,6-dialkyl thieno(3,2-b)thiofuran)-2,1,3-diazosulfide and nitrile butadiene styrene are added to tetrahydrofuran, chloroform, dimethylformamide or ortho-dichlorobenzene in the molar ratio of 1:2-2.5 to obtain reaction product. The obtained product is added to anhydrous tetrahydrofuran, ether or dioxane, cooled at -30 degrees C using liquid hydrogen and isopropanol, butyl lithium is added and reacted at -30 degrees C for 1-3 hours. Butyltin trichloride or tin methyl chloride is added and reacted at -30 degrees C for 0.5-2 hours, heated and reacted for 6-36 hours, to obtain reaction product of 4,7-bis(5-tributyltin-3,6-dialkyl thieno(3,2-b)thiofuran)-2,1,3-diazosulfide. The perylene tetracarboxylic imidodicarbonic diamide dibromo product and 4,7-bis(5-tributyltin-3,6-dialkyl thieno(3,2-b)thiofuran)-2,1,3-diazosulfide are performed using Stille coupling reaction in presence of catalyst and solvent at 50-120 degrees C for 24-72 hours in the molar ratio of 1:1-1.5:1, to obtain perylene tetracarboxylic imidodicarbonic diamide conjugated polymer. Preferred Composition: The solvent is tetrahydrofuran, glycol dimethyl ether, benzene or toluene. The total content of catalyst is 0.01-5%. The catalyst is organic palladium catalyst or mixture of organic palladium catalyst and organic phosphine. The molar ratio of mixture of organic palladium catalyst and organic phosphine is 1:2-20. The organic palladium catalyst is tris(dibenzylideneacetone)dipalladium/tri-o-tolylphosphine, tetrakis(triphenylphosphine)palladium or bis(triphenylphosphine)palladium chloride.
