TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic solvent is N,N dimethylformamide and/or triethylamine. The organopalladium is palladium acetate. The organophosphorus ligand is tris(2,4,6-trimethylphenyl)phosphine.    TECHNOLOGY FOCUS - POLYMERS - Preparation (Claimed): Preparation of (I) comprises mixing organopalladium and organophosphorus ligand in a mole ratio of 1:2-1:20 and using as catalyst in oxygen-free environment, mixing substituted 2,6-diiodo-anthraquinone compound of formula (V) and substituted phenyl-bis-(4-vinyl-phenyl)-amine compound of formula (VI), substituted 3,7-divinyl-10H-phenothiazine compound of formula (VII) and substituted 3,6-divinyl-9H-carbazole compound of formula (VIII) (H) in an organic solvent and performing Heck reaction. Preferred Method: The Heck reaction temperature is 90-110 degrees C for 48-72 hours. (V) is prepared by mixing 1,5-dihydroxy-anthraquinone and substituted monobromo compound of formula (Br-R1) using dimethylformamide as solvent with in the presence of potassium carbonate to obtain substituted anthraquinone compound of formula (IX), mixing (IX), iodine and iodic acid using ethylic acid and chloroform as solvent. (H) is prepared by adding phosphorus oxychloride into N,N-dimethylformamide to obtain mixture system under an ice salt condition, adding 1,2-dichloromethane solution of substituted triphenyl-amine compound of formula (X), substituted 10H-phenothiazine compound of formula (XI) and substituted 9H-carbazole compound of formula (XII) into the mixture system and then reacting to obtain substituted 4-((4-formylphenyl)-phenyl-amino)benzaldehyde compound of formula (XIII), substituted 10H-phenothiazine-3,7-dicarbaldehyde compound of formula (XIV) and substituted 9H-carbazole-3,6-dicarbaldehyde compound of formula (XV) (Q), mixing potassium tert-butoxide or sodium hydride and methyl triphenylphosphonium bromide to obtain mixture solution in anaerobic condition, adding tetrahydrofuran solution of (Q) into the mixture solution and then reacting. The method further comprises purifying the conjugated polymer P comprising adding the conjugated polymer P to methanol solution for precipitating, filtering and collecting sediment, washing collected sediment using methanol and normal hexane, adding chloroform to dissolve, collecting the chloroform solution and rotationally evaporating.
