Abstract:
PURPOSE: An organic electroluminescence device is provided to have improved life time, reduce operational voltage, improved stability and improved production efficiency. CONSTITUTION: An organic electroluminescence device comprises a compound represented by chemical formula 1. The organic electroluminescence device comprises one or more organic material layers comprising the compound. The compound forms the organic material layer by a soulbe process. The organic electroluminescence device is an organic electroluminesncece device comprising a first electrode, the organic material layers and a second electrode laminated in order. The organic layer is one or more selected from a hole injection layer, a hole transport layer, an electron-transfer layer, and an electron injection layer.
Abstract:
PURPOSE: A compound is provided to improve efficiency and color purity of organic electric elements, and to remarkably improve driving voltage, thereby being very suitable as a hole injection material, hoe transfer material, light emitting material and/or electron transfer material. CONSTITUTION: A compound is in chemical formula 1. In chemical formula 1, R is one of a C1-50 alkyl group, a C5-60 aryl group, a C3-50 heteroaryl group, L is a single bond, or a substituted or unsubstituted C6-50 arylene group, a substituted or unsubstituted C3-50 heteroarylene group, Ar1 is a substituted or unsubstituted C1-50 alkyl group, a substituted or unsubstituted C5-60 aryl group, a substituted or unsubstituted C3-50 heteroaryl group, Ar2 and Ar3 is independently substituted or unsubstituted C1-50 alkyl group, substituted or unsubstituted C5-60 aryl group, a substituted or unsubstituted C3-50 hetero aryl group.
