Transparent electrode is cathode and second electrode is anode, or transparent electrode is anode and second electrode is cathode. Preferred Process: Vacuum deposition is vacuum thermal deposition.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Compound (I) has structure of formulae (II)-(VI). Conducting layer is photoactive.M3,M4=Se or Te.Preferred Conditions: Semiconducting layer is photoactive. Organic electronic device is single layer, bi-layer or multiple layer staking or bulking heterojunction layer organic electronic device. Preparation: (Disclosed) Polycyclic compound is prepared by charging diazole, tetrakis(triphenylphosphine) palladium (0) and dry toluene in 20 ml microwave glass tube, sealing the tube, stirring at room temperature for 15 minutes, heating reaction mixture, cooling reaction mixture at room temperature, loading crude product mixture onto a short silica gel bed, washing with methanol and eluting, removing collected soluble volatile fraction, slurrying resulting solid in mixture of methanol and hexanes, sonicating and stirring overnight at room temperature. Preferred Definitions:    L1,L2=Cl, Br, I or greater than or equal to 20C aliphatic, aryl or heteroaryl; and    Y1-Y4=N and are connected by metal bride atom to form 5-member ring system.    EXAMPLE - 7,7'-(4,4-Bis(2-ethylhexyl)-4H-silolo (3,2-b:4,5-b')dithiophene-2,6-diyl)bis(6-fluoro-4-(5'-hexyl-(2,2'-bithiophen)-5-yl)benzo(c)(1,2,5)seleno-diazole) was synthesized by charging 350 mg 4-bromo-5-fluoro-7-(5'-hexyl-(2,2'-bithiophene)-5-yl)benzoic(c)(1,2,5)seleno-diazole, 246 mg 5,5'-bis(trimethylstannyl)-3,3'-di-2-ethylhexylsilylene-2,2'-bithiophene, 30 mg tetrakis(triphenylphosphine) palladium (0) and 15 mg dry toluene in 20 ml microwave glass tube, sealing the tube, stirring at room temperature for 15 minutes, heating reaction mixture at 100 degrees C for 1 minutes, 125 degrees C for 1 minute, 140 degrees C for 10 minutes, 150 degrees C for 10 minutes and 160 degrees C for 10 minutes, cooling reaction mixture at room temperature, loading crude product mixture onto a short silica gel bed, washing with methanol and eluting, removing collected soluble volatile fraction, slurrying resulting solid in mixture of methanol and hexanes, sonicating for 1 hour and stirring overnight at room temperature.
