    摘要: The present invention discloses a novel material is represented by the following formula (A), the organic EL device employing the material as blue emitting layer can lower driving voltage, prolong half-lifetime and increase the efficiency. Wherein m represent an integer of 0 to 4, R1 and R2 are identical or different. R1 and R2 are independently selected from the group consisting of a hydrogen atom, alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms. R3 and R4 are identical or different, R3 and R4 are independently selected from the group consisting of hydrogen atom, a halide, a substituted or unsubstituted arylamine, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms.

    摘要: This disclosure includes a process that unexpectedly can produce very inexpensive graphene, functionalized graphenes, and a new compound called graphenol in particulate or dispersions in solvents. The process can also produce graphene layers on metallic and nonmetallic substrates. Further, the graphenol, functionalized graphenes, and graphene can be utilized to form nanocomposites that yield property improvements exceeding anything reported previously.
