NOVELTY - An organic solar cell material comprises 60C-triphenylamine-thiofuran ternary system. It is a donor-acceptor (D-A) dual functional material with rich fullerene.    USE - An organic solar cell material for a solar cell (claimed).    ADVANTAGE - The organic solar cell material has larger solubility in an organic solvent as compared with fullerene, so the production technique of large area solar cell is simplified, and so the cell strongly absorbs visible light, where a maximal absorptive wavelength is 500 nm close to a maximal solar radiation energy of 475 nm. The material strengthens the compatibility between the ternary system and solar radiation; increases solar spectrum response favorable for increasing photoelectric conversion efficiency; polymerizes macromolecule with single ligand; and forms polymer light-emitting diodes (PLED) by spin coating the product, which solves the problems of a small molecular weight luminescent material, including thermal degradation during vapor deposition and bad crystallization resistance.    DETAILED DESCRIPTION - An organic solar cell material comprises 60C-triphenylamine-thiofuran ternary system. It is a Donor-Acceptor (D-A) dual functional material with rich fullerene, and is of formula (I).    R1, R2=H or 1-6C alkyl; and    R3=H, halo, or dicyanoethylene.    An INDEPENDENT CLAIM is included for a method of preparing the organic solar cell material, comprising preparing trithienyl aniline; formylation of the trithienyl aniline by reacting trithienyl aniline, N,N'-dimethylformamide (DMF) and phosphorus oxychloride in 1,2-dichloroethane; and reacting fullerene, creatine and thiofuran-triphenylamine with formyl and its derivative in toluene reflux and under protection of nitrogen, and purifying the product by column chromatography, which forms the 60C-triphenylamine-thiofuran ternary system. The trithienyl aniline is prepared by forming 2-bromothiofuran Grignard reagent by reacting magnesium strips and 2-bromothiofuran; under protection of nitrogen, carrying out cross-coupling reaction of the agent and tribromotriphenylamine with dichlorobis(triphenylphosphine)palladium (II) (PdCl2(PPh3)2) as catalyst in reflux of tetrahydrofuran (THF) during heating for 16 hours; quenching the reaction with saturated ammonium chloride; extracting the liquid using trichloromethane; drying the extract with anhydrous sodium sulfate; purifying it by column chromatography; and eluting by a mixture of n-hexane and dichloromethane whose volume ratio is 3:1, which forms yellow green needle crystals of trithienyl aniline. The formylation step includes sequentially adding the DMF and the phosphorus oxychloride in 1,2-dichloroethane on an ice bath; treating the mixture with the ice bath for 0.5 hour; stirring the mixture at room temperature for 0.5 hour; adding the trithienyl aniline dissolved in 1,2-dichloroethane in the mixture; refluxing the mixture for 12 hours; cooling it and adding saturated sodium acetate solution in the mixture; layering, washing and then drying with anhydrous sodium sulfate; separating solid orange mono-formylated trithienyl aniline or tri-formylated trithienyl aniline by dichloromethane column chromatography, where the DMF is twice the theoretical amount, where the product is controlled by adjusting phosphorus oxychloride in which when the phosphorus oxychloride is 150 wt.% of the trithienyl aniline, the product is mono-formylated trithienyl aniline, and when the phosphorus oxychloride is greater than or equal to 5 times the weight of the trithienyl aniline, the product is tri-formylated trithienyl aniline; using the mono-formylated trithienyl aniline for making the target product; using the tri-formylated trithienyl aniline which is tri(4-(5-formyl-2-thienyl)phenyl) amine for making di(4-(5-dicyanoethylene-2-thienyl)phenyl)-(4-(5-formyl-2-thienyl)phenyl) amine; putting the tri(4-(5-formyl-2-thienyl)phenyl) amine and malononitrile in a round bottle flask; dissolving them in dichloromethane; dripping a drop of triethylamine; reacting and monitoring the reaction by thin layer chromatography (TLC), stopping the reaction after 2 hours; adding petroleum ether in the flask to form red black deposition; purifying the product by column chromatography; and then eluting with dichloromethane to form a blood red solid with thiofuran-triphenylamine derivative.
