Title:
ORGANIC ELECTROLUMINESCENT ELEMENT USING LIGHT EMITTING MATERIAL COMPOSED OF POLYCYCLIC AROMATIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/045681
Kind Code:
A1
Abstract:
This organic electroluminescent element, which comprises a light emitting layer that contains a polycyclic aromatic compound represented by general formula (1) as a host material (a first component) and a polycyclic aromatic compound containing boron as a dopant material (a second component), has excellent organic EL characteristics such has emission characteristics.
(In formula (1), each of R1-R11 independently represents a hydrogen atom, an aryl group, a heteroaryl group, a diarylamino group, a diarylboryl group (wherein two aryl moieties may be bonded to each other via a single bond or a linking group), an alkyl group, a cycloalkyl group, an alkoxy group or an aryloxy group; at least one hydrogen atom in the aryl group, the heteroaryl group and the diarylamino group may be substituted by an aryl group , a heteroaryl group, an alkyl group or a cycloalkyl group; and at least one hydrogen atom in the compound represented by formula (1) may be substituted by a cyano group, a halogen atom or a deuterium atom.)
