Document Type and Number:
WIPO Patent Application WO/2002/038524
Kind Code:
A1
Abstract:
A novel compound which has a diphenylanthracene structure in the center and an aryl-substituted specific structure at an end thereof; and an organic electroluminescent element comprising a pair of electrodes and formed therebetween a thin organic-compound film which is either a luminescent layer or a multilayer structure including a luminescent layer, wherein at least one layer of the thin organic-compound film contains the novel compound. The novel compound has a high luminescent efficiency, excellent heat resistance, and a long life and emits a blue luminescence with a satisfactory color purity. The organic electroluminescent element utilizes this novel compound.
