TECHNOLOGY FOCUS - ELECTRONICS - Preferred Layer: The organic thin film layer is light emitting layer, hole transport layer, hole implant layer, electron transport layer or electron injection layer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compound: The organic thin film layer further contains reductive dopant chosen from oxide, halide and organic complex of alkali metal, alkaline earth metal or rare earth metal.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general preparation given. Preferred Compound: The compound (I) is preferably of formula (II).A11-A15=CR11 to CR15, SiR11 to SiR15, or N;R11-R15=R1;andAr3=optionally substituted 6-50C aryl. Preferred Definitions:    Ar6-Ar10=thiophenyl, furyl, pyrrolyl, imidazolyl, thiazolyl, oxazolyl, oxadiazolyl, triazolyl, carbazolyl, pyridinyl, pyridazinyl, quinolinyl, isoquinolinyl, acridinyl, imidazopyridinyl or imidazopyrimidinyl.    SPECIFIC COMPOUNDS - 52 Aromatic compounds (I) are disclosed, e.g. 3-(3-(2,6-bis(naphthalen-2-yl)pyridin-4-yl)-5-(quinolin-3-yl)phenyl)quinoline of formula (IA), 4-(3-(4,6-bis(naphthalen-1-yl)pyridin-2-yl)-5-(quinolin-4-yl)phenyl)quinoline, 4-(3-(4,6-bis(naphthalen-1-yl)-1,3,5-triazin-2-yl)-5-(quinolin-4-yl)phenyl)quinoline, 6-(3-(4,6-bis(naphthalen-2-yl)-1,3,5-triazin-2-yl)-5-(quinolin-6-yl)phenyl)quinoline and 6-(3-(4,6-bis(naphthalen-2-yl)pyrimidin-2-yl)-5-(quinolin-6-yl)phenyl)quinoline.    EXAMPLE - (In g) tribromobenzene (20), quinoline-3-boronic acid (24.2), tetrakis (triphenylphosphine)palladium (7.4) and potassium carbonate (52.7) were melted in tetrahydrofuran/water at 85 degrees C. The reaction mixture was extracted with ethyl acetate to obtain an intermediate (I) (13). 2,6-Dibromo-4-iodopyridine (10) in tetrahydrofuran was reacted with n-butyl lithium and triisopropyl borate. The reaction mixture was extracted with ethyl acetate after adding sodium hydroxide aqueous solution, to obtain an intermediate (II) (2.83). The intermediate (I) (4.81), intermediate (II) (2.21), tetrakis (triphenylphosphine)palladium (1.26), potassium carbonate (4.52) were reacted at 75 degrees C in tetrahydrofuran/water, for 18 hours. The reaction mixture was extracted with ethyl acetate and the solvent was removed to obtain an intermediate (III). The intermediate (III) (3.74), naphthalene-2-boronic acid (2.96), tetrakis (triphenylphosphine)palladium (0.9) and potassium carbonate (6.48) were reacted in tetrahydrofuran/water, and the reaction mixture was extracted with chloroform. The solvent was removed from the chloroform layer to obtain 3-(3-(2,6-bis(naphthalen-2-yl)pyridin-4-yl)-5-(quinolin-3-yl)phenyl)quinoline (2). The organic photoelectric device produced using the obtained compound had improved lifetime and high luminous efficiency.
