PURPOSE: A pyrene derivative compound is provided to have excellent luminous properties like driving voltage, luminance, color purity, etc, thereby capable of improving external quantum efficiency, luminance, and life time of an organic electroluminescence device. CONSTITUTION: A pyrene derivative compound is in chemical formula 1 and 2. In chemical formulas, X is selected from a substituted or unsubstituted C6-24 aryl group, a substituted or unsubstituted C2-24 heteroaryl group, a substituted or unsubstituted C1-24 alkyl group, a C2-24 substituted or unsubstituted C1-24 heteroalkyl group, a substituted or unsubstituted C3-24 cycloalkyl group, a substituted or unsubstituted alkoxy group, cyano group, halogen group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted silyl group, deuterium, and hydrogen. Ar1, Ar2, and R is selected from a substituted or unsubstituted C6-24 aryl group, and a substituted or unsubstituted C2-24 heteroaryl group, n and m is respectively an integer of 1 or higher, p is 0 or 1, n+q is 12, and m+r is 14. |
