BLUE FLUORESCENCE COMPOUND, ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A blue fluorescence compound is provided to enable the driving at low voltage by introducing an aromatic compound to an organic electroluminescence device at low voltage and to lifetime and luminous efficiency of the organic electroluminescence device. CONSTITUTION: A blue fluorescence compound has a structure where a diphenylamine derivative is symmetrically substituted for 1,6-pyrene and is represented by chemical formula 1. In chemical formula 1, R1, R2, R3, R4 and R5 are selected from hydrogen, cyanine, fluorine, C1~C6 alkyl group, C6~C40 substituted or unsubstituted aromatic group or heterocyclic group; and R6 is selected from C6~C40 substituted or unsubstituted aromatic group or heterocyclic group, wherein at least one of R1, R2, R3, R4 and R5 is selected from cyanine and at least one is selected from substituted or unsubstituted aromatic group.
