TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (claimed): Compound (I) is prepared by taking perylene compound of formula (IA) and pyrrole compound of formula (IB) as raw materials; heating compounds (IA) and (IB) at mol ratio of 2:1 under catalyst and solvent; refluxing reaction for 21-72 hours; and separating and purifying to obtain compound (I). Preferred Component: The catalyst is organic catalyst consisting of organic palladium catalyst and organic phosphine ligand at molar ratio of 1:(2-20). The organic palladium catalyst is tetrakis(triphenylphosphine)palladium (0), bis(triphenylphosphine)palladium (II) dichloride, or tris(dibenzylideneacetone)dipalladium (0). The organic phosphine ligand is tris(o-tolyl)phosphine or tricyclohexylphosphine. The catalyst is added at 0.01-10 mol.% of compounds (IA) and (IB). The solvent is tetrahydrofuran, dimethyl ether, dioxane, dimethylformamide, benzene, or toluene. Compound (IA) is prepared by reacting perylene compound of formula (IC) and amine compound of formula (R1NH2) at mol ratio of 10:1 under anaerobic condition and propionic acid solution; heating and refluxing overnight; cooling at room temperature; and separating and purifying to obtain compound (IA), which involves reacting mixed solution with aqueous sodium hydroxide solution to remove excess acid, extracting mixture with chloroform, collecting organic phase, evaporating to remove chloroform and organic phase, washing resulting solid with ethyl acetate, dissolving in chloroform, purifying through column chromatography and over alumina, and passing solution by column chromatography in solvent to obtain purified product. Compound (IB) is prepared by reacting pyrrole compound of formula (ID) and trimethyltin chloride at molar ratio of 3:1 with n-butyllithium at - 78 degrees C and under n-butyllithium initiator and tetrahydrofuran solvent, in which trimethyl tin chloride added to compound (ID) is slowly returned at room temperature; stirring overnight; quenching; and separating and purifying to obtain compound (IB), which involves subjecting mixture into rotary evaporation to remove excess tetrahydrofuran solution, extracted with chloroform and water, collecting organic phase, washing, drying over anhydrous sodium sulfate, and removing chloroform to obtain compound (IB). Preferred Method: The separation and purification step involves precipitating reaction mixture in methanol; filtering solid; washing with methanol; collecting solid; drying to remove excess methanol; dissolving solid in chlorobenzene; adding resulting solution into sodium formate diethyl dithiocarbamate aqueous solution; heating at 80 degrees C; stirring overnight; collecting organic phase and subjecting through alumina column chromatography; eluting with chloroform; evaporating to remove excess organic solvent; adding methanol for sedimentation; filtering; subjecting resulting solid through Soxhlet extraction with acetone and methanol; settling for 3 days; filtering; and vacuum pumping overnight to obtain purified compound.
