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.
本发明提供了式(I)的化合物,其中每个取代基在说明书中定义。该化合物可与其他有机发光材料结合,在有机发光元件的发光层中使用。本发明还提供了一种有机发光元件,包括第一电极、第二电极和至少三层有机材料层,这些层位于第一电极和第二电极之间,其中用作发光层的层含有式(I)的化合物。此外,本发明用于制造有机发光元件的全溶液工艺具有诸如避免层间混溶等优点,以制造具有较大表面积和较低生产成本的元件。
