Abstract: The present invention relates to a pyrazole derivative and an organic electroluminescent element using the same. The organic electroluminescent element using the pyrazole derivative in the present invention has greater light-emitting efficiency and long life by driving at lower voltage. More specifically, the pyrazole derivative of the present invention can be used in electro elements through the process of deposition and solution and used as light-emitting materials such as phosphorescent hosts in manufacturing organic electroluminescent elements with high heat stability, crystal stability, solubility for an organic solvent, excellent thin film forming function in a solution phase and energy transfer and compatibility with metal-ligand.

Abstract: PURPOSE: A method for preparing a soluble graphene solution from carbon fibers and a method for preparing the composite of carbon fiber oxide and a polymer are provided to greatly reduce the cost because the starting material is pitch which is waste used for asphalt pavement; and to dispense with developing a mine for obtaining graphite because graphite is not used. CONSTITUTION: A method for preparing a soluble graphene solution comprises the steps of: forming carbon fiber oxide by oxidizing carbon fiber; forming a mixed solution of the carbon fiber oxide, a polymer non-covalently interacting with the carbon fiber oxide and a polar solvent; and reducing the carbon fiber oxide into graphenes by adding a reducing agent into the mixed solution.
