TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The rubicene compound is of formula: X1-(A-(B')m)n-X2. The rubicene compound is an electron-donating organic material.A=rubicene structure;B'=bivalent coupling group;m=0 or 1;andX1,X2=H, alkyl, alkoxy, aryl, heteroaryl or halo.Preferred Composition: The photovoltaic device material further contains an electron-accepting organic material, preferably fullerene compound. EXAMPLE - Ether solution (200 ml) of 4-bromobenzene (in g) (14.4) and n-butyl lithium hexane solution (45 ml) were mixed at room temperature for 15 minutes. To the mixture, 1,5-dichloro anthraquinone (6.9) was added and mixed. To the resulting mixture, water (100 ml) was added, mixed, extracted, distilled, precipitated, filtered and washed to obtain 1,5-dichloro-9,10-bis(4-chlorophenyl)-9,10-dihydroanthracene-9, 10-diol (4.8). Potassium iodide (9), sodium hypophosphite monohydrate (9) and acetic acid solution of 1,5-dichloro-9,10-bis(4-chlorophenyl)-9,10-dihydroanthracene-9, 10-diol (3) were mixed, filtered, washed and dried to obtain 1,5-dichloro-9,10-bis(4-chlorophenyl)anthracene (2.1). Potassium hydroxide (6) and quinoline suspension solution (40 ml) of 1,5-dichloro-9,10-bis(4-chlorophenyl)anthracene (2) were mixed at 200 degrees C for 30 minutes, and further mixed with 1 M-sulfuric acid (600 ml), filtered, extracted and distilled to obtain 5,12-dichloro-rubicene (1.22). 5,12-Dichloro-rubicene (600 mg), bis(dibenzylidene acetone) palladium complex (80 mg), S-phos ligand (100 mg), potassium acetate (730 mg), dioxane (80 ml) and 4,4,5,5-tetramethyl-2-(4,4,5,5-tetramethyl-1,3, 2-dioxaborolan-2-yl)-1,3,2-dioxaborolane (1.93) were mixed, distilled and purified to obtain 4,4,5,5-tetramethyl-2-(12-(4,4,5,5-tetramethyl-1,3, 2-dioxaborolan-2-yl)rubicen-5-yl)-1,3,2-dioxaborolane (31 mg). 4,4,5,5-Tetramethyl-2-(12-(4,4,5,5-tetramethyl-1,3, 2-dioxaborolan-2-yl)rubicen-5-yl)-1,3,2-dioxaborolane (108 mg), 4,10-dibromo-7,7-bis(2-ethylhexyl)-3, 11-dithiatricyclo(6.3.0.02,6)undeca-1(8),2(6),4,9-tetraene (106 mg), 1 M-aqueous solution (4 ml) of potassium carbonate, Alquat 336 (RTM: methyl tricaprylyl monomethyl ammonium chloride), tetrakis(triphenyl phosphine) palladium complex (10 mg), toluene solution (25 ml), bromobenzene (40 mg) and phenyl boronic acid (60 mg) were mixed at 90 degrees C for 1 hour, cooled, filtered, washed, refluxed, filtered and distilled to obtain rubicene compound having weight average molecular weight of 4000, number average molecular weight of 3000 and optical absorption end wavelength of (760 nm). A photovoltaic device formed using the rubicene compound had excellent photoelectric conversion efficiency.
