Description

technical field

[0001] The present invention relates to a material for organic electroluminescent elements and an organic electroluminescent element using the same. Background technique

[0002] An organic electroluminescent element (hereafter, "electroluminescence" is abbreviated as "EL") is a self-luminous element utilizing the principle that, by applying an electric field, the The recombination energy of the fluorescent substance emits light.

[0003] Since the report (Non-Patent Document 1, etc.) of low-voltage driving organic EL elements based on multilayer elements researched by C.W.Tang of Iselman Kudak (Istman Kodatsuku) Co., Ltd. Research on materials for organic EL elements has been actively carried out.

[0004] The organic EL device reported by Tang et al. has a laminated structure in which tris(8-quinoline aluminum) is used as a light-emitting layer and a triphenyldiamine derivative is used as a hole transport layer. As the advantages of the laminated structu...
