ORGANIC LIGHT-EMITTING MATERIAL, ORGANIC LIGHT-EMITTING ELEMENT USING THE SAME AND METHOD OF FORMING THE SAME

Abstract

The present invention provides compound of formula (I)wherein each substituent is defined in the specification. The compound may be used, in combination with other organic light-emitting materials, in a light-emitting layer of an organic light-emitting element. The present invention also provides an organic light-emitting element including a first electrode, a second electrode and at least three layers of organic material layers disposed between the first electrode and the second electrode, wherein the layer used as a light-emitting layer contains a compound of formula (I). Further, an all-solution process, which is used for fabricating the organic light-emitting element of the present invention, has the advantages such as avoiding miscibility among the layers to fabricate an element with a large surface area and lower production cost.
