  • Novel blue organic compound and organic electroluminescent device using the same
    Publication number: 20100289006
    Abstract: Novel blue organic compound is provided. Using the blue organic compound, an organic electroluminescent device is provided, which achieved a blue emission with high efficiency, saturated color and long device lifetime. The novel blue organic compound is represented by the following general formula (1). wherein R1, R2, R3, and R4 represent a substituted or unsubstituted aryl group from 6 to 20 carbon atoms, in which R1, R2, R3, and R4 may be identical with or different from each other, or R1-R2 and R3-R4 may be bridged to 5 to 7-membered carbocyclic ring. R5 to R16 represent hydrogen or a substituted or unsubstituted alkyl or aryl group from 1 to 10 carbon atoms. Besides, R1-R5, R2-R6, R3-R15, R4-R16, R5-R7, R6-R8, R9-R11, R10-R12, R13-R15 and R14-R16 may be bridged to a carbocyclic ring from 3 to 10 carbon atoms.
